If this is about inclusion in 4.0, then I support it. Technically this is *mostly* just a move+donation of some code from java-driver to Cassandra. Given how important this seemingly is to the board and PMC for us to not have the dependency on the driver, the sooner it’s gone, the better.
I’d be +1 for committing to trunk. — AY On 11 September 2018 at 14:43:29, Robert Stupp (sn...@snazy.de) wrote: The patch is technically complete - i.e. it works and does its thing. It's not strictly a bug fix but targets trunk. That's why I started the discussion. On 09/11/2018 02:53 PM, Jason Brown wrote: > Hi Robert, > > Thanks for taking on this work.
