Chapter 17. The L1 Cache

The Level 1 (or L1) cache stores remote cache entries after they are initially accessed, preventing unnecessary remote fetch operations for each subsequent use of the same entries. The L1 cache is created when JBoss Data Grid's cache mode is set to distribution. The L1 cache is not available with other cache modes therefore any configuration related to L1 cache is ignored.

The temporary location used by the L1 cache can be changed from the default location.
