Eduard Rakhmankulov updated IGNITE-14728:
-----------------------------------------
Description:
We have a system property named "IGNITE_PDS_WAL_REBALANCE_THRESHOLD", that
determines a count of entries of partition starting from which cluster will try
applying historical rebalance for that partition.
But the system property is not convenient to use and is hidden from most part
of users.
I propose the creation of a new DMS property *history.rebalance.threshold*
instead of a system property.
The next algorithm will be used:
# On node start *history.rebalance.threshold* property will be checked.
# If there is no value, then the old system property
*IGNITE_PDS_WAL_REBALANCE_THRESHOLD* value will be written to DMS.
# If a system property is not defined then the default value from java will be
written to DMS (*500*).
# On property check print to log value and source of value.
Mark the system property *IGNITE_PDS_WAL_REBALANCE_THRESHOLD* as deprecated.
