Hi Shalom, If that helps.. From the documentation : "You should prepare only once, and cache the PreparedStatement in your application (it is thread-safe). If you call prepare multiple times with the same query string, the driver will log a warning”

Make sure to only prepare them once ;) On 29 August 2017 at 13:41, Matija Gobec <matija0...@gmail.com<mailto:matija0...@gmail.com>> wrote: I don't see any disadvantages or warning signs.

They are faster to execute since the statement is already parsed and in C* and you just pass the parameters. No additional statement processing is needed.
