> BinaryMetadata exchange should not be triggered if metadata was not updated
> ---------------------------------------------------------------------------

> Key: IGNITE-7699
> URL: https://issues.apache.org/jira/browse/IGNITE-7699
> Project: Ignite
> Issue Type: Improvement
> Reporter: Sergey Chugunov
> Assignee: Sergey Chugunov
> Priority: Major
> Fix For: 2.5
>
>
> It was found that DiscoveryCustomEvent-based implementation of BinaryMetadata
> exchange protocol triggers propose-accept process even when it is not needed.
> In some situations BinaryObjects may be built with exactly the same scheme
> many times, and registering of BinaryMetatada only once is enough.
> However current implementation executes expensive propose-accept process for
> each *addMeta* request even if requesting meta is the same.
> Implementation should be improved so that prop-ack process is executed only
> if BinaryMetadata really changed.
