> Looking at a heap dump of 2.0 cluster, I found that majority of the objects
> are IndexInfo and its ByteBuffers. This is specially bad in endpoints with
> large CQL partitions. If a CQL partition is say 6,4GB, it will have 100K
> IndexInfo objects and 200K ByteBuffers. This will create a lot of churn for
> GC. Can this be improved by not creating so many objects?
