Ivan Bessonov updated IGNITE-11416:
-----------------------------------
Description:
We need following improvements:
* do not write the same value twice in a row, this would lead to history
pollution;
* add "putAll" functionality on binary level, not in public API yet. This
would simplify the migration in future;
* do not use "*HistoryItem" class for everything, this is not conventional;
* retrieve "dmsVer" from cluster on handshake, this would help to reduce
joining node DataBag size drastically;
* add "isEmpty()" or "long getVersion()" method to metastorage, will be
helpful for components that use it;
* there has to be an ability to read data on client nodes, maybe write as
well, not sure yet;
* implement more optimal in-memory storage for history cache;
* start in-memory metastorage at proper time, current implementation does it a
bit too late.
