Subject [jira] [Created] (IGNITE-11821) Move rebalanceBatchSize and rebalanceBatchesPrefetchCnt to IgniteConfiguration level
Date Mon, 29 Apr 2019 11:54:00 GMT
Maxim Muzafarov created IGNITE-11821:
----------------------------------------

             Summary: Move rebalanceBatchSize and rebalanceBatchesPrefetchCnt to IgniteConfiguration
level
                 Key: IGNITE-11821
                 URL: https://issues.apache.org/jira/browse/IGNITE-11821
             Project: Ignite
          Issue Type: Improvement
            Reporter: Maxim Muzafarov
            Assignee: Maxim Muzafarov
             Fix For: 2.8


The set of cluster rebalancing properties below must be maintained and provided by {{IgniteConfiguration}},
so an administrator will be able to tune the cluster rebalance behaviour depending on used
hardware (e.g. the different hardware can have different maximum transmission unit (MTU) and
it's strongly recommended to use specific rebalanceBatchSize for each cluster environment).

Currently, there is no way to change these properties for already created persistent caches.

{code:title=CacheConfiguration.java}
    /** Rebalance timeout. */
    private long rebalanceTimeout = DFLT_REBALANCE_TIMEOUT;

    /** Rebalance batch size. */
    private int rebalanceBatchSize = DFLT_REBALANCE_BATCH_SIZE;

    /** Rebalance batches prefetch count. */
    private long rebalanceBatchesPrefetchCnt = DFLT_REBALANCE_BATCHES_PREFETCH_COUNT;
{code}
