What is the JdbcStringBasedCacheStore Cache Loader?
JdbcStringBasedCacheStore - stores each key in its own row, increasing throughput under concurrent load. In order to store each key in its own column, it relies on a (pluggable) bijection that maps the each key to a String object. The bijection is defined by the Key2StringMapper interface. Infinispans ships a default implementation (smartly named DefaultKey2StringMapper) that knows how to handle primitive types.
