--------------------------------------
Summary: DistributedMetaStorage improvements
Key: IGNITE-11416
URL: https://issues.apache.org/jira/browse/IGNITE-11416
Project: Ignite
Issue Type: Improvement
Reporter: Ivan Bessonov
Assignee: Ivan Bessonov
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.
