Since there are no comments,
I'll keep it as is for now (count continuous query cursors the same way as
other cursors)

Igniters,
Igor raised an interesting point in the PR:
Should we limit the number of Continuous Queries together with other queries
according to ClientConnectorConfiguration.maxOpenCursorsPerConn?
Or should we have a separate limit?
Technically, Ignite returns a QueryCursor, but it is very differ
The pull request is ready for review.

I don't think that our protocol should involve ignoring messages.

I think you mean "server -> client" here.
But I still didn't get why do we need it.
I've briefly looked to the POC implementation and, as far as I understand,
OP_QUERY_CONTINUOUS_END_NOTIFICATION can be sent only wh
Igniters,
I've made an important change to the IEP (and the POC):
OP_QUERY_CONTINUOUS_END_NOTIFICATION is another client -> server message
that notifies the client that the query has stopped and no more events
should be expected.
This is important because client can't immediately stop listening

I've removed Initial Query from the POC and IEP (left a note there about
the decision).
Since there are no other comments and concerns, I'll move on with the final

Igor, Alex,
I was aware of the duplicates issue with the initial query, but I did not

OP_RESOURCE_CLOSE is used for that. I've updated the IEP in an attempt to
make this cleaner.

Interesting, I'm not aware of this. Can you
Pavel,
What's about "stop" message? How can user unsubscribe from receiving
notifications?
Also, I believe I've seen discussions on removing initial query from
continuous queries,
as there are not any guarantees about getting consistent results with them.
