Semen Boikov commented on IGNITE-3073:
--------------------------------------
There is no need to wait on utility cache rebalance future to get metadata,
fixed in master (commit f3eb94e).
> Possible thread starvation due to rebalancing
> ---------------------------------------------

> Key: IGNITE-3073
> URL: https://issues.apache.org/jira/browse/IGNITE-3073
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 1.5.0.final
> Reporter: Valentin Kulichenko
> Assignee: Semen Boikov
> Priority: Critical
> Fix For: 1.6
>
>
> We're currently rebalancing the utility cache in the system pool. This can
> cause starvation, for example in this scenario:
> # Start several nodes and a cache with indexing configured.
> # Continuously load the system with puts.
> # Add one more node. It will join and will start processing put requests
> immediately.
> # For each request, indexing processor will try to get binary metadata and
> will block on utility cache rebalance future. This will block all threads in
> the system pool.
> # Utility cache rebalancing will be scheduled but will never start, because
> all threads in system pool are blocked.
> I think we should rebalance utility cache synchronously in exchange worker,
> like we do with the marshaller cache.
