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.
