Hi, but if the data must be converted, this is something that should be fixed inside cassandra… Is this a bug, should I file a bug report? Or is there some kind of setting I can change to make it work for now?
Maybe it is related to this issue, but this should have been fixed in 1.1.0: https://issues.apache.org/jira/browse/CASSANDRA-3954 Thanks Ivo Am 26.06.2012 um 09:26 schrieb Fei Shan: > Hi > > please refer JDK nio package's ByteBuffer, I don't think that ByteBuffer > can be cast from the BigInteger directly, > it seems you need make some conversion before put it into a ByteBuffer. > > Thanks > Fei > > On Tue, Jun 26, 2012 at 12:07 AM, Ivo Meißner <i...@overtronic.com> wrote: > Hi, > > I am running into some problems with secondary indexes that I am unable to > track down.
