------------------------------------------
[~agoncharuk] Looks good to me. Please proceed with merge.

> Remaining Estimate: 0h

> The scenario is similar to IGNITE-11204, but several exchanges should be
> merged. If in this case a merged-exchange node is left and all other nodes
> messages are already received, the exchange will not be completed because
> {{F.isEmpty(mergedJoinExchMsgs)}} is {{false}}.
> Looks like we should decrement the {{awaitMergedMsgs}} and check this field
> for {{0}}.
