Exploring Mybatis' Second-Level Cache Mechanism

The article delves into the operation of Mybatis' second-level cache, a Java persistence framework. It details how Mybatis employs this cache to enhance performance by storing SQL query results for later reuse. Unlike the first-level cache, which is specific to a single session, the second-level cache is shared across multiple sessions. Technical details include the use of the Cache interface and implementations such as PerpetualCache and LruCache. The primary impact is a reduction in database access, improving application efficiency.
