> {{CacheSharedPreloader}} must do the following:
> # [1] build the map of partitions and corresponding supplier nodes from
> which partitions will be loaded;
> # [1] switching 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;
> # [2] 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] Listening for the transmission handler to receive files;
> # [2] Run rebuild indexes async over the receiving partitions (API must be
> provided by IGNITE-11075);
> # [1] Run historical rebalance from LWM to HWM collected above (LWM can be
> read from received file meta page)
> The points marked with the label {{[1]}} must be done prior to {{[2]}}.
>
> NOTE. Check the following things:
> # Rebalancing of MVCC cache groups;
> # How LWM and HWM will be set for the historical rebalance;
