Fwd: place for printing info about partition distribution (IGNITE-4756)
Guys, lets suggest the format for this log.
Yakov's version is "print only nodes that differ on +/-10% from average
partitions count we can print problem message looks like:
[cacheName=NAME, nodes=[nodeId=<ID, totalPartitionsCount=<count>,
percentageOfTotalPartsCount=<percentage>, parts=[<count>, ...,<count>]]
Where the first element of parts array is a count of primary partitions,
the second is count of backup0 partitions etc.
The default value of the property IGNITE_PART_DISTRIBUTION_WARN_THRESHOLD
must disable distribution calculation because it takes <caches_count> *
<parttitons_count> * <nodes_count> operations per node. "
Do you agree ?

Yakov, Taras do you have any idea about it ?

Hello guys!
I want to discuss and suggest some format and place for pinting info about
partition distribution to log from issue https://issues.apache.org/jira
/browse/IGNITE-4756
What do you think about it ?
Issue is about RendezvousAffinityFunction and FairAffinityFunction classes.

According to the last Yakov's comments at the ticket:
1. Calculation and printing distribution deviation will be produced only
for local node.
2. In this case it takes only one additional compare nodeID if we build
statistic with the assignment calculation.
3. We have return injection of the Ignite instance into the AF to gather
local node.
