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

             Summary: transactions may use more memory than expected
                 Key: GEODE-5127
                 URL: https://issues.apache.org/jira/browse/GEODE-5127
             Project: Geode
          Issue Type: Improvement
          Components: transactions
            Reporter: Darrel Schneider


Part of the transaction implementation is a "failoverMap" that remembers the last 1000 transactions by default. If the transactions are large this can consume a large amount of memory.
It would be better if this large map was not needed at all or if the implementation could confirm a transaction completed and does not need to be kept in the map.

For a workaround the size of the map can be reduced by setting this system property:
gemfire.transactionFailoverMapSize
