Maxim Muzafarov updated IGNITE-12069:
-------------------------------------
Description:
{{CacheSharedPreloader}} must do the following:
# build the map of partitions and corresponding supplier nodes from which
partitions will be loaded [1];
# switch cache data storage to {{no-op}} and back to original (HWM must be
fixed here for the needs of historical rebalance) under the checkpoint and keep
the partition update counter for each partition [1];
# run async the eviction indexes for the list of collected partitions (API
must be provided by IGNITE-11075) [2];
# send a request message to each node one by one with the list of partitions
to load [2];
# wait for files received (listening for the transmission handler) [2];
# run rebuild indexes async over the receiving partitions (API must be
provided by IGNITE-11075) [2];
# run historical rebalance from LWM to HWM collected above (LWM can be read
from the received file meta page) [1];
The points marked with the label {{[1]}} must be done prior to {{[2]}}.
NOTE. The following things need to be checked:
# Rebalancing of MVCC cache groups;
# How LWM and HWM will be set for the historical rebalance;
