Mirza Aliev updated IGNITE-15417: --------------------------------- Description: There is a bug in {{MetaStorageListener}} for {{RangeCommand}}, {{WatchRangeKeysCommand}}, {{WatchExactKeysCommand}} commands in case cluster has several raft nodes, currently we create new {{cursorId}} for this commands on server side on a single client request, which means that one logical cursor is created for every {{MetaStorageListener}} on server side. This bug leads to a critical problem for cluster with several nodes because cursors won't be replicated correctly. We should create {{cursorId}} only on client side en pass it to server. was: There is a bug in {{MetaStorageListener}} for {{RangeCommand}}, {{WatchRangeKeysCommand}}, {{WatchExactKeysCommand}} commands in case cluster has several raft nodes, currently we create new {{cursorId}} for this commands on server side on a single client request, which means that one logical cursor is created for every MetaStorageListener on server side.
