Vyacheslav Daradur updated IGNITE-4756:
---------------------------------------
Description:
Summarize discussions:
Add log message in case partitions distribution is not close to even
distribution:
# Add system property IGNITE_PART_DISTRIBUTION_WARN_THRESHOLD with default
value 0.1 to print warn message only when nodes count differs more then
threshold;
# The statistic is calculated and printed only for the local node;
# Statistic is placed at the {{GridAffinityAssignmentCache#calculate}} and
calculated for new {{idealAssignment}}.
# Message format is
{noformat}
Local node affinity assignment distribution is not ideal [cache=<cache_name>,
expectedPrimary=<ideal_count_of_primary_partitions>,
exectedBackups=<ideal_count_of_backups>, primary=<count_of_primary_partitions>,
backups=<count_of_backup_partitions>].
{noformat}
e.g. for cache with name "test", 2 backups, 4 partition, 3 nodes:
{noformat}
Local node affinity assignment distribution is not ideal [cache=test,
expectedPrimary=1.33 (33.3%), exectedBackups=2.66 (66.66%), primary=1 (25%),
backups=3(75%)].
