Having just installed the 4.6dp, I was trying to do some basic queries as part of my startup/init script, which work in 4.5. They were just hanging until timing out with the 4.6dp.
I was using Java client 2.2.5/1.2.5/rx 1.1.1. I upgraded to the latest everything (2.3.5/2.2.5, rx 1.2.3) and it works again.
This certainly isn’t expected, though the “hanging” sounds like possibly a couple known issues with processing some chunked N1QL replies from the cluster which were fixed in 2.3.2 and 2.3.3.
Was it the situation that everything would ‘hang’ until timeout after a particular point? Do you have anything to help us repro?
Matt,
Last night I filed another, more subtle, problem that I was having with the latest versions of the client library:
https://www.couchbase.com/forums/t/issue-with-merging-queries-with-cb-4-6-java-2-3-5/11031
When I wind this example back to the old versions, I get an exception thrown:
com.couchbase.client.core.RequestCancelledException: Request cancelled in-flight.
I would guess that this is what was happening in my real code, but I was failing to catch the exception, so it just looked like a ‘hang’ until timeout.
Hopefully that helps somewhat.
