Does preload=true works for infinispan cassandra cache loader?

jia Feb 6, 2013 3:35 PM

I am trying to use cassandra cache loader. When I set preload="false", everything worked. The cache entry I put in persisted to Cassandra DB. When I start the cache new and get the entry, I can get them. But when I set preload="true", I got exception, see attached file. I just wonder if this option is supported for cassandra cache loader. I am testing aginst 5.2.0-ALPHA1. Or maybe a later version fixed this? Please advice.

Thanks, Jessica

The error has occurred within Cassandra:

org.apache.thrift.TApplicationException: Internal error processing get_range_slices

Is it possible to have the Cassandra-side logs on this please ?

Jessica, the CassandraCacheStore only supports OrderPreservingPartitioner. I will port the cache store to use CQL3 during the 5.3 cycle and hopefully support all partitioners.
