> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Affects Versions: 2.5
> Reporter: Pavel Kovalenko
> Assignee: Pavel Kovalenko
> Priority: Major
> Fix For: 2.7
>
>
> Currently, we're waiting for latch completion from newly joining nodes. However, such nodes don't have any updates to be synced on wait partitions release. Newly joining nodes may start their caches before exchange latch creation and this can delay exchange process.
> We should explicitly ignore such nodes and don't include them into latch participants.
