      Existing memtable implementation is tested as before. New implementations will need to also perform all memtable tests in addition to implementation-specific unit tests.

      New configuration options need to be added to the documentation.

    Description

      Pluggable memtable API as described in CEP-11.

       

      Initial version is already available in this branch, and needs to be updated to the changes in trunk. Two additional features suggested by CEP reviewers are also to be implemented:

      • Sharding support: extending the memtable owner interface to supply suitable shard boundaries that split the owned token space and are in agreement with disk boundaries.
      • Shared read API with sstables: defining a common interface for reading partitions from memtables and sstables; this is to include filters to avoid unnecessary copying.
