Abstract
The invention discloses a method for realizing configurable cache. The method comprises the following steps of: configuring cache overdue duration information in a database or a cache configuration file; loading the cache overdue duration configuration information into a cache configuration processor when a server is started; realizing each specific cache entry in a category, taking the full name of the category as a Key when the cache entry is added into the cache and reading the overdue duration of the cache from the cache configuration processor according to the key; and finally amending time setting corresponding to the full name of the cache category in the database or the configuration file only when the overdue duration of a certain cache needs to be amended. By the method, the application service can flexibly adjust the refresh frequency of the cache entry according to actual conditions when gaining benefit from the high performance of the memory cache.
Description
Technical field
The present invention relates to a kind of method that realizes configurable cache, particularly a kind of method that realizes the buffer memory of configurable expired duration.
Background technology
Because than the high order of magnitude of efficient of database I/O, memory cache is application service system a kind of method that improves performance commonly used to the efficient of calculator memory I/O at least.But this buffer memory often accessed data that seldom are modified reads in information in advance to internal memory from data sources such as database or file system, to directly from internal memory, read these information of application access the time like this and do not produce database I/O operation, this will improve the application service performance to a great extent, especially concurrent than in higher.
Use buffer memory to bring a spinoff also: the modification of data can not be reflected in the memory cache at once.Because application cache generally will be specified the expired duration of this data item in data source loading data item, in case expired just reload.And this expired duration be appointed as much to come according to concrete business demand fixed, if so this time is write extremely in code, that will bring some inconvenience to service operation flexibly, and best bet is: make the expired duration of memory cache configurable and can adjust flexibly.
Summary of the invention
Technical matters to be solved by this invention provides a kind of method that realizes configurable cache, and it can carry out flexible configuration to the expired duration of buffer memory, is convenient at any time the expired strategy of buffer memory be adjusted according to actual conditions.
A kind of method that realizes configurable cache of the present invention, this method comprises following step at least:
Step 1: the expired duration information of buffer memory is configured in database or the cached configuration file.Configuration information only comprises two fields: Key and minute to be the time span of unit, and the corresponding concrete buffer memory of each key is realized full name of class;
Step 2: server is when starting, the expired duration configuration information of buffer memory is loaded in the cached configuration processor, this processor itself also is a buffer memory, it adds the expired duration configuration of buffer memory in the cache entry to, and expired time is appointed as 1 minute, like this, the expired duration configuration information of buffer memory will refresh once every 1 minute;
Step 3: each concrete cache entry realizes with a class, and when adding to cache entry in the buffer memory, as Key, the expired duration of buffer memory can read from the buffer memory configuration processor according to this key with this type of full name;
Step 4: when needs are revised the expired duration of certain buffer memory, only need in database or configuration file, revise the setting of this cache class full name time corresponding;
A kind of method that realizes configurable cache that the present invention relates to, it can realize the expired duration of buffer memory is carried out flexible configuration, the expired duration configuration information that modification finishes will come into force after 1 minute, concrete cache entry next time will be as the criterion with the expired duration of new configuration when expired, make application service when the high-performance of memory cache is benefited like this, also can adjust flexibly the refreshing frequency of cache entry according to actual conditions.
Embodiment
Key step of the present invention is as follows:
Step 1: the expired duration information of buffer memory is configured in database or the cached configuration file.Configuration information only comprises two fields: Key and minute to be the time span of unit, and the corresponding concrete buffer memory of each key is realized full name of class;
Step 2: server is when starting, the expired duration configuration information of buffer memory is loaded in the cached configuration processor, this processor itself also is a buffer memory, and it adds the expired duration configuration of buffer memory in the cache entry to, and expired time is appointed as 1 minute;
Step 3: each concrete cache entry realizes with a class, when adding to cache entry in the buffer memory, with this type of full name as Key;
Step 4: when needs are revised the expired duration of certain buffer memory, only need in database or configuration file, revise the setting of this cache class full name time corresponding;
When above-mentioned technical scheme is implemented, the expired duration of concrete buffer memory can carry out flexible configuration, the expired duration configuration information that modification finishes will come into force after 1 minute, concrete cache entry next time will be as the criterion with the expired duration of new configuration when expired, make application service when the high-performance of memory cache is benefited like this, also can adjust flexibly the refreshing frequency of cache entry according to actual conditions.
It should be noted last that above embodiment is only in order to explanation and unrestricted technical scheme described in the invention; Therefore, although this instructions has been described in detail the present invention with reference to the above embodiments,, those of ordinary skill in the art should be appreciated that still and can make amendment or replacement to the present invention with being equal to; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the middle of the claim scope of the present invention.
Claims (1)
1. method that realizes configurable cache, it is characterized in that: this method comprises following step at least:
Step 1: the expired duration information of buffer memory is configured in database or the cached configuration file.Configuration information only comprises two fields: Key and minute to be the time span of unit, the corresponding concrete buffer memory of each key is realized full name of class.
Step 2: server is when starting, the expired duration configuration information of buffer memory is loaded in the cached configuration processor, this processor itself also is a buffer memory, it adds the expired duration configuration of buffer memory in the cache entry to, and expired time is appointed as 1 minute, like this, the expired duration configuration information of buffer memory will refresh once every 1 minute.
Step 3: each concrete cache entry realizes with a class, and when adding to cache entry in the buffer memory, as Key, the expired duration of buffer memory can read from the buffer memory configuration processor according to this key with this type of full name.
Step 4: when needs are revised the expired duration of certain buffer memory, only need in database or configuration file, revise the setting of this cache class full name time corresponding.
