> Key: IGNITE-12069
> URL: https://issues.apache.org/jira/browse/IGNITE-12069
> Project: Ignite
> Issue Type: Sub-task
> Reporter: Maxim Muzafarov
> Assignee: Pavel Pereslegin
> Priority: Major
> Labels: iep-28
>
> {{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;
