Summary: Optimise slab allocator to enable higher number of column families Key: CASSANDRA-6794 URL: https://issues.apache.org/jira/browse/CASSANDRA-6794 Project: Cassandra Issue Type: Improvement Components: Core Reporter: Jeremy Hanna Assignee: Benedict Currently the slab allocator allocates 1MB per column family. This has been very beneficial for gc efficiency. However, it makes it more difficult to have large numbers of column families. It would be preferable to have a more intelligent way to allocate slabs so that there is more flexibility between slab allocator and non-slab allocator behaviour. A simple first step is to ramp up size of slabs from small (say 8KB) when empty, to 1MB after a few slabs. -- This message was sent by Atlassian JIRA (v6.2#6252)
