The driver caches prepared statements: if you call prepare() multiple times with the same query QUORUM įor more details, including the complete list of attributes that are copied, refer to getConsistencyLevel () = DefaultConsistencyLevel.
prepare ( simpleStatement ) BoundStatement boundStatement = preparedStatement. build () PreparedStatement preparedStatement = session. setConsistencyLevel ( DefaultConsistencyLevel.
builder ( "SELECT * FROM product WHERE sku = ?" ). SimpleStatement, its execution parameters will propagate to bound statements: SimpleStatement simpleStatement = SimpleStatement. Session.prepare() accepts either a plain query string, or a SimpleStatement object.
Same queries over and over, and a parameterized version can be extracted and prepared. But note that this should be pretty rare: most client applications typically repeat the If you have a unique query that is executed only once, a simple statement will be moreĮfficient. For example, CASSANDRA-10813 suggests adding
