Taras Ledkov commented on IGNITE-4756:
--------------------------------------
If I catch your question right:
# You patch will be placed at the {{RendezvousAffinityFunction}};
# Add the system property to disable calculate/print the partition statistic;
# Calculates statistic (the partitions count for the replicas (primary,
backup_0, ... etc.)) on the assignment calculation take a look at the
{{assignPartition}} method.
# Revert the {{Ignite ignite}} member of the {{RendezvousAffinityFunction}}
(see the file history) to gather the local node and calculate statistic only
for local node.
# Print the statistic et the end of the {{assignPartitions}} method.
> Print info about partition distribution to log
