In subject area: Computer Science A Database Cache refers to the storage of application cache and indexed database caches on a local system to improve performance by reducing the need to fetch data from the main database repeatedly. AI generated definition based on: Windows 2012 Server Network ...
Oracle In-Memory Database Cache is a TimesTen in-memory database used as a cache to an Oracle database. Oracle In-Memory Database Cache improves application response time by caching a performance-critical subset of tables and table fragments from an Oracle database into a TimesTen in-memory ...
Solid Cache supports these options in addition to the standardActiveSupport::Cache::Storeoptions: error_handler- a Proc to call to handle any transient database errors that are raised (default: log errors as warnings) expiry_batch_size- the batch size to use when deleting old records (default...
* A blocking cache puts a lock when a value is null * and releases it when the value is back again. * This way other threads will wait for the value to be * available instead of hitting the database. * 删除key对应的缓存数据
You can configure in-line caching for a database back end or as a side cache for a database. In-line caching uses eXtreme Scale as the primary means for interacting with the data. When eXtreme Scale is used as an in-line cache, the application interacts
Database A - ZOracle In-Memory Database Cache 概述 Oracle In-Memory Database Cache (IMDB Cache) 是一个 Oracle Database 产品选件,非常适于将 Oracle 数据库中对性能影响极大的数据子集缓存在应用层中,以提高应用响应速度。借助该解决方案,应用使用 SQL 和 PL/SQL 语句在缓存表上执行读/写操作时,将能...
If the query cannot be satisfied in the cache, Oracle Database Cache routes the query to the origin database and marks the query as a miss. If the query can be satisfied in the cache, Oracle Database Cache returns the data to the user and marks the query as a hit. The number of...
A high-performance backend cache system. It is intended for use in speeding up dynamic web applications by alleviating database load. Well implemented, it can drops the database load to almost nothing, yielding faster page load times for users, better
You can perform queries and use indexes to retrieve data in a cache that matches certain criteria.
