Interface PreparedStatementCache

All Known Implementing Classes:

MapPreparedStatementCache

Deprecated.

since 3.2, the Cassandra driver has a built-in prepared statement cache with makes external caching of prepared statements superfluous.

@Deprecated
public interface PreparedStatementCache

Cache interface to synchronously prepare CQL statements.

Implementing classes of PreparedStatementCache come with own synchronization and cache implementation characteristics. A cache implementation should optimize for reduction of preparation calls and cache statements using Cassandras cache key which is specific to the Cluster, keyspace, and CQL text.

Since:

2.0
