org.springframework.data.cassandra.core.cql.CachedPreparedStatementCreator
All Implemented Interfaces:
PreparedStatementCreator

Deprecated, for removal: This API element is subject to removal in a future version.
since 2.0. This class uses an unsafe, static held cache.
This PreparedStatementCreator maintains a static cache of all prepared statements for the duration of the JVM runtime, more specific the lifecycle of the associated ClassLoader. When preparing statements with Cassandra, each Statement should be prepared once and only once due to the overhead of preparing the statement.

CachedPreparedStatementCreator is thread-safe and does not require external synchronization when used by concurrent threads.
