[jira] [Created] (IGNITE-17335) Off-heap storage for RAFT log

Roman Puchkovskiy created IGNITE-17335:
------------------------------------------

             Summary: Off-heap storage for RAFT log
                 Key: IGNITE-17335
                 URL: https://issues.apache.org/jira/browse/IGNITE-17335
             Project: Ignite
          Issue Type: Improvement
            Reporter: Roman Puchkovskiy
             Fix For: 3.0.0-alpha6


In IGNITE-17334, we'll build a volatile log storage using a simple on-heap data structure. We need to replace it with an off-heap structure (probably, using page memory) to avoid GC pressure.

When using page memory, we could allocate a single region for all RAFT groups' log storages and allocate some memory budget to each RAFT group.

The description is not too precise, some research is needed.
