Log warnings - "Re-preparing already prepared query UPDATE"

[Rastusik]

I'm using spring and with every call to mappingSession.append(), following warnings are being written to the log:

2014-06-10 23:53:53.994  WARN   --- [Driver worker-7] com.datastax.driver.core.Cluster         : Re-preparing already prepared query UPDATE test_db.test SET days=days+{16098} WHERE id=?;. Please note that preparing the same query more than once is generally an anti-pattern and will likely affect performance. Consider preparing the statement only once.

I think that fixing this issue would bring a little performance gain at least, but the main thing is to get rid of the warning from the log.

Thanks for fixing this.

Done. PreparedStatements now are cached and reused. Refresh from maven central
