Class SimplePreparedStatementCreator

java.lang.Object

org.springframework.cassandra.core.SimplePreparedStatementCreator

All Implemented Interfaces:

PreparedStatementCreator

public class SimplePreparedStatementCreator
extends Object
implements PreparedStatementCreator

This Prepared Statement Creator simply prepares a statement from the CQL string. This should not be used in Production systems with high volume reads and writes. Use CachedPreparedStatementCreator When preparing statements with Cassandra, each Statement should be prepared once and only once due to the overhead of preparing the statement.
