> Key: IGNITE-10912
> URL: https://issues.apache.org/jira/browse/IGNITE-10912
> Project: Ignite
> Issue Type: Improvement
> Reporter: Alexei Scherbakov
> Priority: Major
> Fix For: 2.8
>
>
> WIth large topology and large number of caches/groups node join message can reach a size > 30M due to a large amount of transferred discovery data.
> It adds overhead on ring traversal and slows down "node join" PME.
> Possible solution:
> # introduce pre-join message with discovery data which doesn't increment topology version. After all nodes wil have corressponding discovery data start actual joining. Discovery data probably should be stored off-heap(or even on disk) to avoid heap usage bursts on joining of multiple nodes.
> # Add compression to discovery data.
