12.4.3. JdbcStringBasedCacheStores

The JdbcStringBasedCacheStore stores each entry its own row in the table, instead of grouping multiple entries into each row, resulting in increased throughput under a concurrent load. It also uses a (pluggable) bijection that maps each key to a String object. The Key2StringMapper interface defines the bijection.

JBoss Data Grid includes a default implementation called DefaultTwoWayKey2StringMapper that handles primitive types.
