> Disadvantages in log of historical rebalance
> --------------------------------------------
>
> Key: IGNITE-12935
> URL: https://issues.apache.org/jira/browse/IGNITE-12935
> Project: Ignite
> Issue Type: Improvement
> Reporter: Vladislav Pyatkov
> Assignee: Vladislav Pyatkov
> Priority: Major
> Time Spent: 1h 40m
> Remaining Estimate: 0h
>
> # Mention in the log only partitions for which there are no nodes that suit
> as historical supplier
> For these partitions, print minimal counter (since which we should perform
> historical rebalancing) with corresponding node and maximum reserved counter
> (since which cluster can perform historical rebalancing) with corresponding
> node.
> This will let us know:
> ## Whether history was reserved at all
> ## How much reserved history we lack to perform a historical rebalancing
> ## I see resulting output like this:
> {noformat}
> Historical rebalancing wasn't scheduled for some partitions:
> History wasn't reserved for: [list of partitions and groups]
> History was reserved, but minimum present counter is less than maximum
> reserved: [[grp=GRP, part=ID, minCntr=cntr, minNodeId=ID, maxReserved=cntr,
> maxReservedNodeId=ID], ...]{noformat}
> ## We can also aggregate previous message by (minNodeId) to easily find the
> exact node (or nodes) which were the reason of full rebalance.
> # Log results of {{reserveHistoryForExchange()}}. They can be compactly
> represented as mappings: {{(grpId -> checkpoint (id, timestamp))}}. For every
> group, also log message about why the previous checkpoint wasn't successfully
> reserved.
> There can be three reasons:
> ## Previous checkpoint simply isn't present in the history (the oldest is
> reserved)
> ## WAL reservation failure (call below returned false)
> {code:java}
> chpEntry = entry(cpTs);
> boolean reserved = cctx.wal().reserve(chpEntry.checkpointMark());// If
> checkpoint WAL history can't be reserved, stop searching.
> if (!reserved)
> break;{code}
> ## Checkpoint was marked as inapplicable for historical rebalancing
> {code:java}
> for (Integer grpId : new HashSet<>(groupsAndPartitions.keySet()))
> if (!isCheckpointApplicableForGroup(grpId, chpEntry))
> groupsAndPartitions.remove(grpId);{code}
