正如背景技术所言，在离线数据仓库场景下，通常采用全量读取待删除用户信息，然后针对全量数据进行对应的数据操作。由于需要处理待删除用户的全量数据，造成了大量不必要的IO，资源消耗和时间消耗巨大。比如，参照图1，Hive表的一行数据存储在一个文件中的，包括以下字段：uid(用户ID)、device_id(用户设备ID)、idfa(广告客户标识符)、login_time(登录时间)、category(页面操作类别)和other_info(其他页面操作信息)。当用户需要更新或删除该Hive表中某一行数据的uid列时，需要先读取整行数据，然后针对该行数据中的uid列执行更新或删除操作，造成了大量不必要的IO，资源消耗和时间消耗巨大。As mentioned in the background technology, in the offline data warehouse scenario, it is usually used to read the user information to be deleted in full, and then perform corresponding data operations on the full data. Due to the need to process the full amount of data of the user to be deleted, a large amount of unnecessary IO is caused, which consumes a lot of resources and time. For example, referring to Figure 1, a row of data in the Hive table is stored in a file, including the following fields: uid (user ID), device_id (user device ID), idfa (advertiser identifier), login_time (login time), category (page operation category) and other_info (other page operation information). When the user needs to update or delete the uid column of a certain row of data in the Hive table, it is necessary to read the entire row of data first, and then perform an update or delete operation on the uid column in the row of data, resulting in a large amount of unnecessary IO and resources. The consumption and time consumption are huge.

有鉴于此，本公开提供一种数据操作方法，以减少离线数据仓库场景下数据操作过程中不必要的IO，从而减少数据操作过程中的资源消耗和时间消耗，提高数据操作效率。In view of this, the present disclosure provides a data operation method to reduce unnecessary IO during data operation in an offline data warehouse scenario, thereby reducing resource consumption and time consumption during data operation, and improving data operation efficiency.

图2是根据本公开一示例性实施例示出的一种数据操作方法的流程图。参照图2，该数据操作方法包括：Fig. 2 is a flow chart showing a data operation method according to an exemplary embodiment of the present disclosure. Referring to Fig. 2, the data manipulation method includes:

步骤201，响应于针对离线数据仓库中目标数据的数据操作请求，根据数据操作请求携带的目标数据的标识信息，在离线数据仓库中检索用于存储目标数据的目标文件。其中离线数据仓库中用户关联的第一数据存储在第一文件中，该用户关联的第二数据存储在第二文件中，第一数据能够唯一标识用户。 Step 201, in response to a data operation request for target data in the offline data warehouse, retrieve a target file for storing the target data in the offline data warehouse according to the identification information of the target data carried in the data operation request. The first data associated with the user in the offline data warehouse is stored in the first file, the second data associated with the user is stored in the second file, and the first data can uniquely identify the user.

步骤202，基于标识信息查询目标文件中的数据，若查询到的数据的标识信息与目标数据的所述标识信息相同，则确定目标文件中数据对应的待操作数据行。 Step 202, query the data in the target file based on the identification information, and if the identification information of the queried data is the same as the identification information of the target data, determine the data row corresponding to the data in the target file to be operated.

步骤203，对待操作数据行中的数据执行数据操作请求对应的数据操作。 Step 203, perform data operation corresponding to the data operation request on the data in the data row to be operated.

示例地，在获取用户授权应用平台对自身相关的数据进行数据操作的情况下，第一数据可以包括用户在账户注册时输入的用户ID、用户年龄、用户所在区域的信息等，第二数据可以包括用户的页面操作数据，比如用户发布的公开图片、公开视频等，本公开实施例对于第一数据和第二数据的具体内容不作限定。For example, in the case where the user authorizes the application platform to perform data operations on its own related data, the first data may include the user ID entered by the user during account registration, the user's age, information on the area where the user is located, etc., and the second data may be Including the user's page operation data, such as public pictures and public videos posted by the user, the embodiment of the present disclosure does not limit the specific content of the first data and the second data.

参照图3，在离线数据仓库中，能够唯一标识用户的第一数据(比如uid、device_id等)存储在第一文件中，无法唯一标识用户的第二数据(比如login_time)存储在第二文件中，因此响应于针对离线数据仓库中目标数据的数据操作请求，可以先根据数据操作请求携带的目标数据的标识信息，在离线数据仓库中检索用于存储目标数据的目标文件，然后读取目标文件中的数据行进行数据操作。由此，可以读取用户关联的第一数据进行数据操作，避免读取该用户关联的第二数据进行数据操作，进而可以减少离线数据仓库场景下数据操作过程中不必要的IO，减少资源消耗和时间消耗，提高数据操作效率。Referring to Figure 3, in the offline data warehouse, the first data that can uniquely identify the user (such as uid, device_id, etc.) is stored in the first file, and the second data that cannot uniquely identify the user (such as login_time) is stored in the second file , so in response to the data operation request for the target data in the offline data warehouse, the target file for storing the target data can be retrieved in the offline data warehouse according to the identification information of the target data carried in the data operation request, and then the target file can be read The data row in the data operation. In this way, the first data associated with the user can be read for data operations, and the second data associated with the user can be avoided for data operations, thereby reducing unnecessary IO during data operations in the offline data warehouse scenario and reducing resource consumption And time consumption, improve data operation efficiency.

为了使得本领域技术人员更加理解本公开提供的数据操作方法，下面对上述各步骤进行详细举例说明。In order to make those skilled in the art better understand the data operation method provided by the present disclosure, the above steps are described in detail below with examples.

例如，在用户进行账户注销操作后需要删除用户相关的数据。按照相关技术中的方式，需要先读取离线数据仓库中对应Hive表中该用户对应的整行数据，该整行数据包括该用户在账户注册时输入的用户ID、用户年龄、用户所在区域的信息等个人注册数据，也包括与用户的浏览、点击等相关的用户操作数据。然后，对读取到的该行数据执行删除操作，从而删除用户相关的数据。For example, user-related data needs to be deleted after the user cancels the account. According to the method in the related technology, it is necessary to first read the entire row of data corresponding to the user in the corresponding Hive table in the offline data warehouse. Information and other personal registration data, as well as user operation data related to the user's browsing and clicking. Then, a delete operation is performed on the read row of data, thereby deleting user-related data.

但是，相关技术中的此种方式，由于需要读取整行数据，会造成大量不必要的IO(Input/Output，输入/输出)，比如在需要删除用户的个人注册数据的情况下，会同时读取对应的用户操作数据，资源消耗和时间消耗大。因此，本公开提出将能够唯一标识用户的第一数据(比如上文举例的个人注册数据)和该用户关联的第二数据(比如上文举例的用户操作数据)垂直切分存储在多个文件中，从而可以读取对应文件中的数据行进行数据操作，减少不必要的IO，进而减少资源消耗和时间消耗。However, this method in the related art will cause a large amount of unnecessary IO (Input/Output, input/output) due to the need to read the entire row of data. For example, when the personal registration data of the user needs to be deleted, the Reading the corresponding user operation data consumes a lot of resources and time. Therefore, this disclosure proposes to vertically split and store the first data that can uniquely identify a user (such as the personal registration data exemplified above) and the second data associated with the user (such as the user operation data exemplified above) in multiple files In this way, the data rows in the corresponding file can be read to perform data operations, reducing unnecessary IO, thereby reducing resource consumption and time consumption.

在可能的方式中，离线数据仓库中的数据是通过如下方式存储到离线数据仓库的：对待存储到离线数据仓库的数据所包括的每一子数据进行分类，得到该数据中能够唯一标识用户的第一子数据和无法唯一标识用户的第二子数据；将第一子数据写入所述离线数据仓库的第一文件，并将第二子数据写入离线数据仓库的第二文件，建立第一文件中的第一子数据与第二文件中的第二子数据之间的映射关系，映射关系用于表征第一子数据与所述第二子数据来源于同一用户数据。In a possible way, the data in the offline data warehouse is stored in the offline data warehouse in the following way: Classify each sub-data included in the data to be stored in the offline data warehouse, and obtain the sub-data that can uniquely identify the user in the data The first sub-data and the second sub-data that cannot uniquely identify the user; the first sub-data is written into the first file of the offline data warehouse, and the second sub-data is written into the second file of the offline data warehouse, and the second sub-data is established. A mapping relationship between the first sub-data in a file and the second sub-data in a second file, the mapping relationship is used to indicate that the first sub-data and the second sub-data come from the same user data.

示例地，在获取用户授权应用平台对自身相关的数据进行数据操作的情况下，第一数据可以包括用户在账户注册时输入的用户ID、用户年龄、用户所在区域的信息等，第二数据可以包括用户的页面操作数据，比如用户发布的公开图片、公开视频等。在具体应用时，可以根据实际情况划分第一子数据和第二子数据包括的具体数据内容，即可以根据实际情况设定第一文件和第二文件存储的数据内容，本公开实施例对此不作限定。For example, in the case where the user authorizes the application platform to perform data operations on its own related data, the first data may include the user ID entered by the user during account registration, the user's age, information on the area where the user is located, etc., and the second data may be Including the user's page operation data, such as public pictures and public videos posted by the user. In a specific application, the specific data content included in the first sub-data and the second sub-data can be divided according to the actual situation, that is, the data content stored in the first file and the second file can be set according to the actual situation. Not limited.

在预先设定第一文件和第二文件存储的数据内容后，针对待存储到离线数据仓库的数据，可以基于该预先设定的内容对该数据包括的每一子数据进行分类，得到该数据中能够唯一标识用户的第一子数据和无法唯一标识用户的第二子数据，然后将第一子数据写入离线数据仓库的第一文件，并将第二子数据写入离线数据仓库的第二文件，同时建立第一文件中的第一子数据与第二文件中的第二子数据之间的映射关系。由此，第一文件和第二文件中同一用户关联的数据可以通过该映射关系进行对应，并且在数据操作过程中，可以仅读取第一文件中的数据进行数据操作，减少不必要的IO，提高数据操作效率。After presetting the data content stored in the first file and the second file, for the data to be stored in the offline data warehouse, each sub-data included in the data can be classified based on the pre-set content to obtain the data The first sub-data that can uniquely identify the user and the second sub-data that cannot uniquely identify the user, then write the first sub-data into the first file of the offline data warehouse, and write the second sub-data into the first file of the offline data warehouse two files, and simultaneously establish a mapping relationship between the first sub-data in the first file and the second sub-data in the second file. Therefore, the data associated with the same user in the first file and the second file can be mapped through the mapping relationship, and in the process of data operation, only the data in the first file can be read for data operation, reducing unnecessary IO , improve data operation efficiency.

在可能的方式中，可以将第一子数据写入第一文件的目标数据行，并将第二子数据写入第二文件中行号与目标数据行相同的数据行。相应地，建立第一文件中的第一子数据与第二文件中的第二子数据之间的映射关系可以是：通过第一子数据在第一文件中的数据行号和第二子数据在第二文件中的数据行号，将第一子数据与第二子数据进行映射。In a possible manner, the first sub-data may be written into the target data line of the first file, and the second sub-data may be written into the data line of the second file having the same line number as the target data line. Correspondingly, establishing the mapping relationship between the first sub-data in the first file and the second sub-data in the second file can be: through the data line number and the second sub-data in the first file of the first sub-data In the data line number in the second file, the first sub-data is mapped with the second sub-data.

也即是说，可以通过数据行号将第一文件和第二文件中同一用户关联的数据进行映射。由此，无需额外的设置即可实现第一文件和第二文件中同一用户关联的数据之间的映射，从而提高数据操作效率。That is to say, the data associated with the same user in the first file and the second file can be mapped through the data line number. Thus, the mapping between the data associated with the same user in the first file and the second file can be realized without additional settings, thereby improving the efficiency of data operation.

当然，在其他可能的方式中，还可以通过其他方式建立第一文件中的第一子数据与第二文件中的第二子数据之间的映射关系，比如先对第一文件和第二文件中同一用户关联的数据添加同一映射标识，然后根据该映射标识将第一文件和第二文件中同一用户关联的数据进行对应，等等，本公开实施例对此不作限定。Of course, in other possible ways, the mapping relationship between the first sub-data in the first file and the second sub-data in the second file can also be established in other ways, for example, the first file and the second file Add the same mapping identifier to the data associated with the same user in the file, and then associate the data associated with the same user in the first file and the second file according to the mapping identifier, etc. This is not limited in this embodiment of the present disclosure.

在本公开实施例中，由于离线数据仓库中能够唯一标识用户的第一数据存储在第一文件中，无法唯一标识用户的第二数据存储在第二文件中。因此，在接收到数据操作请求后，可以根据该数据操作请求携带的目标数据的标识信息，第一文件和第二文件中确定用于存储目标数据的目标文件，从而读取目标文件中的数据行进行数据操作，以减少数据操作过程中不必要的IO。In the embodiment of the present disclosure, since the first data that can uniquely identify the user in the offline data warehouse is stored in the first file, the second data that cannot uniquely identify the user is stored in the second file. Therefore, after receiving the data operation request, according to the identification information of the target data carried in the data operation request, the target file for storing the target data can be determined in the first file and the second file, so as to read the data in the target file Rows perform data operations to reduce unnecessary IO during data operations.

示例地，在实际应用中，在用户发起账户注销后，该账户对应的应用平台可以在一定时间内删除该用户的相关数据。也即是说，可以间隔一定时间删除离线数据仓库中该时间段内发起账户注销的用户的相关数据。因此，本公开实施例中的数据操作请求可以是间隔一定时间发起的针对离线数据仓库中数据的数据操作请求。其中，间隔时间的具体取值可以根据实际情况设定，本公开实施例对此不作限定。数据操作请求可以是用于执行数据删除的请求或者可以是用于执行数据更新的请求，本公开实施例对此也不作限定。For example, in practical applications, after a user initiates account cancellation, the application platform corresponding to the account may delete the relevant data of the user within a certain period of time. That is to say, it is possible to delete the relevant data of the user who initiated the account cancellation within the time period in the offline data warehouse at a certain time interval. Therefore, the data operation request in the embodiment of the present disclosure may be a data operation request for data in an offline data warehouse initiated at intervals. Wherein, the specific value of the interval time may be set according to the actual situation, which is not limited in the embodiments of the present disclosure. The data operation request may be a request for performing data deletion or a request for performing data update, which is not limited in this embodiment of the present disclosure.

示例地，标识信息可以用于唯一标识目标数据，可以是目标数据对应的用户ID，等等，本公开实施例对此不作限定。在本公开实施例中，在数据操作请求中可以携带待操作的目标数据的标识信息，比如数据操作请求中携带目标数据的用户ID，因此后续可以根据该标识信息在离线数据仓库中检索存储有目标数据的目标文件。For example, the identification information may be used to uniquely identify the target data, and may be a user ID corresponding to the target data, etc., which is not limited in this embodiment of the present disclosure. In the embodiment of the present disclosure, the identification information of the target data to be operated can be carried in the data operation request, for example, the user ID of the target data is carried in the data operation request, so it can be subsequently retrieved and stored in the offline data warehouse according to the identification information. Object file for object data.

在可能的方式中，离线数据仓库中第一文件的文件名包括哈希值，该哈希值是对第一文件中存储的多个用户数据的标识信息进行哈希计算确定的。相应地，根据数据操作请求携带的目标数据的标识信息，在离线数据仓库中检索存储有目标数据的目标文件，可以是：根据数据操作请求携带的目标数据的标识信息进行哈希计算，得到目标数据对应的目标哈希值。然后基于该目标哈希值，在离线数据仓库中检索各第一文件的文件名，并将文件名中的哈希值与目标哈希值相同的第一文件确定为存储有目标数据的目标文件。In a possible manner, the file name of the first file in the offline data warehouse includes a hash value, and the hash value is determined by performing hash calculation on identification information of a plurality of user data stored in the first file. Correspondingly, according to the identification information of the target data carried in the data operation request, retrieving the target file storing the target data in the offline data warehouse may be: performing hash calculation according to the identification information of the target data carried in the data operation request to obtain the target The target hash value corresponding to the data. Then based on the target hash value, retrieve the file names of the first files in the offline data warehouse, and determine the first file whose hash value in the file name is the same as the target hash value as the target file storing the target data .

示例地，在实际应用中，可以根据数据的标识信息进行哈希计算，然后将具有相同哈希值的多个数据存在同一个第一文件中，并且该第一文件的文件名可以包括对应的哈希值。可以理解的是，该第一文件对应一个分桶(Bucket)。比如划分1000个分桶，Hive分区下会有1000个第一文件，且文件名中会记录对应文件中数据的哈希值。在此种情况下，根据待操作数据的哈希值和该1000个文件的文件名即可精确定位该待操作数据所在的目标文件，然后进行数据操作。For example, in practical applications, hash calculation can be performed according to the identification information of the data, and then multiple data with the same hash value are stored in the same first file, and the file name of the first file can include the corresponding hash value. It can be understood that the first file corresponds to a bucket (Bucket). For example, if 1000 buckets are divided, there will be 1000 first files under the Hive partition, and the hash value of the data in the corresponding file will be recorded in the file name. In this case, according to the hash value of the data to be operated and the file names of the 1000 files, the target file where the data to be operated is located can be precisely located, and then the data operation is performed.

也即是说，本公开实施例中，可以根据第一文件对应的哈希值进行索引检索，提高检索效率，进而提高数据操作效率。That is to say, in the embodiment of the present disclosure, index retrieval can be performed according to the hash value corresponding to the first file, so as to improve retrieval efficiency and further improve data operation efficiency.

当然，在实际应用中，还可以通过其他方式检索存储有目标数据的目标文件，比如先将离线数据仓库中的第一文件按照用户ID进行分组存储，比如第一个第一文件的用户ID为0至100，第二个第一文件的用户ID为101至200，以此类推，然后根据目标数据的用户ID确定存储有该目标数据的目标文件，等等，本公开实施例对于检索存储有目标数据的目标文件的方式不作限定。Of course, in practical applications, other methods can also be used to retrieve the target files that store the target data. For example, the first files in the offline data warehouse are stored in groups according to user IDs. For example, the user ID of the first first file is 0 to 100, the user ID of the second first file is 101 to 200, and so on, and then determine the target file that stores the target data according to the user ID of the target data, and so on. The format of the object file of the object data is not limited.

在确定存储有目标数据的目标文件后，可以读取该目标文件的数据进行数据操作。示例地，可以基于该标识信息查询目标文件中的数据，若查询到的数据的标识信息与目标数据的标识信息相同，则确定目标文件中数据对应的待操作数据行，然后对待操作数据行中的数据执行数据操作请求对应的数据操作。After the target file storing the target data is determined, the data of the target file can be read for data operation. For example, the data in the target file can be queried based on the identification information. If the identification information of the queried data is the same as the identification information of the target data, the data row to be operated corresponding to the data in the target file is determined, and then the data row to be operated is determined. Execute the data operation corresponding to the data operation request.

在可能的方式中，数据操作请求为数据删除请求，则对所述待操作数据行中的数据执行所述数据操作请求对应的数据操作可以是：将待操作数据行中的所有数据置为空。In a possible manner, the data operation request is a data deletion request, and performing the data operation corresponding to the data operation request on the data in the data row to be operated may be: setting all the data in the data row to be operated to empty .

例如，目标文件和该目标文件对应的第二文件如图3所示，数据删除请求用于删除目标文件中的用户ID为12的数据，则按照本公开实施例提供的数据操作方法执行数据删除操作后，目标文件和该目标文件对应的第二文件可以如图4所示。应当理解的是，在将目标文件中对应数据行的所有数据置为空后，无法证明第二文件中与该数据行具有映射关系的数据行的数据是某一用户的数据，因此可以满足删除用户数据的需求。For example, the target file and the second file corresponding to the target file are shown in Figure 3, and the data deletion request is used to delete the data whose user ID is 12 in the target file, then perform data deletion according to the data operation method provided by the embodiment of the present disclosure After the operation, the target file and the second file corresponding to the target file may be as shown in FIG. 4 . It should be understood that after emptying all the data in the corresponding data row in the target file, it cannot be proved that the data in the data row in the second file that has a mapping relationship with the data row is the data of a certain user, so the deletion can be satisfied. User data requirements.

在可能的方式中，对目标数据行中的数据执行数据操作请求对应的数据操作还可以是：基于目标文件执行数据写操作，得到目标文件对应的文件副本，并在文件副本中确定待操作数据行对应的副本数据行，然后对副本数据行中的数据执行数据操作请求对应的数据操作。In a possible manner, performing the data operation corresponding to the data operation request on the data in the target data row may also be: performing a data write operation based on the target file, obtaining a file copy corresponding to the target file, and determining the data to be operated in the file copy row corresponding to the copy data row, and then perform the data operation corresponding to the data operation request on the data in the copy data row.

也即是说，在数据操作过程中，可以先新写一个文件，然后对该新写的文件执行数据操作请求对应的数据操作。由此，可以保证数据操作过程中对目标文件中读取数据的正确性。That is to say, during the data operation process, a new file may be written first, and then the data operation corresponding to the data operation request may be performed on the newly written file. Thus, the correctness of the data read in the target file during the data operation can be guaranteed.

在此基础上，在执行数据操作之前，可以响应于对目标文件的数据读取请求，从目标文件中读取对应的数据，在执行数据操作之后，可以响应于对目标文件的数据读取请求，从已执行数据操作请求的文件副本中读取对应的数据。On this basis, before performing the data operation, the corresponding data can be read from the target file in response to the data reading request for the target file, and after the data operation is performed, the data reading request for the target file can be responded to , to read the corresponding data from the file copy that has executed the data operation request.

也即是说，在离线数据仓库中，单分区目录下同时存在多版本数据。数据操作未提交前，下游任务读取的是历史版本数据，即从初始的目标文件中读取对应的数据。数据操作提交后，下游任务读取的是最新版本的数据，即从已执行数据操作请求的文件副本中读取对应的数据，从而可以保证数据操作过程中对目标文件中读取数据的正确性。That is to say, in the offline data warehouse, multiple versions of data exist in a single partition directory at the same time. Before the data operation is submitted, the downstream task reads the historical version data, that is, reads the corresponding data from the original target file. After the data operation is submitted, the downstream task reads the latest version of the data, that is, reads the corresponding data from the file copy that has executed the data operation request, so as to ensure the correctness of the data read in the target file during the data operation process .

下面以数据删除为例说明本公开提供的数据操作方法。The following uses data deletion as an example to illustrate the data operation method provided by the present disclosure.

参照图5，第一文件(PII Columns)和对应的第二文件(Non-PII Columns)对应同一分桶，每一分桶对应有哈希值(Bucket 1至Bucket N，N为大于2的正整数)。用户提交数据删除请求，该数据删除请求可以包括待删除的用户ID列表。离线数据仓库可以根据该用户ID列表中各用户ID进行哈希计算，得到目标哈希值。然后，根据该目标哈希值检索每一分桶，并确定哈希值与目标哈希值相同的分桶，从而将该分桶所包括的第一文件确定为存储有待删除数据的目标文件。其中，图5以检索到分桶Bucket 1和Bucket i(i为大于1且小于N的正整数)进行示意。然后，基于检索到的分桶中的目标文件进行写操作，得到文件副本，再对该文件副本执行数据操作请求对应的数据操作。由此，对应分桶中会存在两个版本的第一文件，比如图5示意的老版本第一文件V1和新版本第一文件V2，其中老版本第一文件V1为初始的目标文件，新版本第一文件V2为已执行对应数据操作的文件副本。之后，下游任务读取数据时可以从新版本第一文件中读取对应的数据，而不会从旧版本第一文件中读取已删除的用户数据，从而可以保证下游任务读取数据的正确性。并且，可以定期对老版本文件进行物理删除。Referring to Figure 5, the first file (PII Columns) and the corresponding second file (Non-PII Columns) correspond to the same bucket, and each bucket corresponds to a hash value (Bucket 1 to Bucket N, where N is a positive value greater than 2 integer). A user submits a data deletion request, and the data deletion request may include a list of user IDs to be deleted. The offline data warehouse can perform hash calculation according to each user ID in the user ID list to obtain a target hash value. Then, each bucket is retrieved according to the target hash value, and the bucket whose hash value is the same as the target hash value is determined, so that the first file included in the bucket is determined as the target file storing the data to be deleted. Among them, Fig. 5 illustrates the retrieval of buckets Bucket 1 and Bucket i (i is a positive integer greater than 1 and less than N). Then, a write operation is performed based on the retrieved target file in the bucket to obtain a file copy, and then the data operation corresponding to the data operation request is performed on the file copy. Therefore, there will be two versions of the first file in the corresponding bucket, such as the old version of the first file V1 and the new version of the first file V2 shown in Figure 5, where the old version of the first file V1 is the initial target file, and the new version of the first file V1 Version 1 file V2 is a copy of the file for which corresponding data operations have been performed. Afterwards, when the downstream task reads data, it can read the corresponding data from the first file of the new version instead of reading the deleted user data from the first file of the old version, thus ensuring the correctness of the data read by the downstream task . In addition, old versions of files can be physically deleted on a regular basis.

应当理解的是，一般情况下，能够唯一标识用户的数据占用户总数据(包括个人信息数据和页面操作数据)总量的极小比例，因此本公开实施例提供的数据操作方法读取第一文件中的数据进行数据操作，可以极大程度上降低数据操作的IO成本。例如，用户ID是某Hive表中的某一列，占数据总存储的1％。那么基于本公开实施例提供的数据操作方法对该用户ID进行数据操作，可以降低总体IO至相关技术中全量读取方案的1％。It should be understood that, in general, the data that can uniquely identify a user accounts for a very small proportion of the total amount of user data (including personal information data and page operation data), so the data operation method provided by the embodiment of the present disclosure reads the first The data in the file is used for data operations, which can greatly reduce the IO cost of data operations. For example, user ID is a column in a Hive table, which accounts for 1% of the total data storage. Then, performing data operations on the user ID based on the data operation method provided by the embodiments of the present disclosure can reduce the overall IO to 1% of the full read solution in the related art.

并且，根据实际测试，本公开实施例提供的数据操作方法的数据操作性能是全量读取方案的将近10倍。此外，相比于全量读取方案会删除用户的所有记录数据，本公开提供的数据操作方法读取第一文件的数据进行数据操作，不影响第二文件的数据，例如点击和浏览等指标数据，对于整体指标的完整性和可回溯性保护更佳。Moreover, according to actual tests, the data operation performance of the data operation method provided by the embodiment of the present disclosure is nearly 10 times that of the full read solution. In addition, compared to the full read solution that deletes all recorded data of the user, the data operation method provided by this disclosure reads the data of the first file for data operations without affecting the data of the second file, such as index data such as clicks and browsing , which is better for the integrity and traceability protection of the overall index.
