Subject [jira] [Created] (IGNITE-12092) Single-partition-map should not be send earlier than initial rebalance is completed
Date Wed, 21 Aug 2019 12:59:00 GMT
Anton Vinogradov created IGNITE-12092:
-----------------------------------------

             Summary: Single-partition-map should not be send earlier than initial rebalance
is completed
                 Key: IGNITE-12092
                 URL: https://issues.apache.org/jira/browse/IGNITE-12092
             Project: Ignite
          Issue Type: Task
            Reporter: Anton Vinogradov


Currently, single partition map is sent to coordination if there wasn't partition owning for
some period.
See {{GridCachePartitionExchangeManager#scheduleResendPartitions}} and {{GridCachePartitionExchangeManager#sendLocalPartitions}}
for details.
This may (will) cause unexpected load at demander node and 
- decrease cluster performance (since some operations will be now served by demander)
- rebalance duration will be increased.

So, single-partition-map should be sent only on initial rebalance completion.

Good place to fix this is to add one more if at {{GridCachePartitionExchangeManager#refreshPartitions}}.
