--------------------------------------

             Summary: Avoid repeated decoding of the same transaction in coprocessors
                 Key: TEPHRA-248
                 URL: https://issues.apache.org/jira/browse/TEPHRA-248
             Project: Tephra
          Issue Type: Improvement
          Components: core, manager
    Affects Versions: 0.12.0-incubating
            Reporter: Andreas Neumann
            Assignee: Andreas Neumann
             Fix For: 0.13.0-incubating


If a transaction performs multiple operations on the same region, the same transaction is transmitted repeatedly, and decoded each time. It would be good to cache the decoded transaction for a short time to avoid the cost of repeated decoding. This of course has memory impact, the cache must evict aggressively and be limited in size.
