Yakov Zhdanov commented on IGNITE-4756:
---------------------------------------
I think this way log will become too verbose.
[~tledkov-gridgain], can you please think over and suggest another format -
Ignite outputs only warning for caches and nodes where distribution is not
even. I would also allow to set threshold via system property
(-DIGNITE_PART_DISTRIBUTION_WARN_THRESHOLD=0.1 - warn about nodes with 10+%
difference).
We can output the messages on each topology change
OK Message
{{Partition map has been built (distribution is even).}}
Problem message
{{Partition map has been built (distribution is not even for caches)
[cacheName=NAME, nodes=[<node_ID_0>, <partitions_count>,
<percentage_of_parts_count>]....}}
[~tledkov-gridgain], can you please suggest message format also containing info
on backups distribution. Can you please think it over?
> Print info about partition distribution to log
