> Key: IGNITE-12844
> URL: https://issues.apache.org/jira/browse/IGNITE-12844
> Project: Ignite
> Issue Type: Bug
> Reporter: Philipp Masharov
> Assignee: Philipp Masharov
> Priority: Major
> Fix For: 2.9
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Several thousand caches send metrics in each discovery message.
> Check implementation of `TcpDiscoveryMetricsUpdateMessage`
> This behavior increases processing time and raises message size. As a result,
> the discovery worker is busy and the queue pool is growing.
> We need to notify about the possible issue and print suggestion, for example,
> `-DIGNITE_DISCOVERY_DISABLE_CACHE=true` if it can help. Assumes to print WARN
> message once, for example, if TcpDiscoveryMetricsUpdateMessage consists of
> more than 500 CacheMetricsSnaphot instances.
