Hi, And we found this one. It is an issue that could lead to data losing(checkpoint & restoring) when people using the RocksDBBackend, cause by the not so nice APIs of RocksIterator...had a hard time to believe it, but this seems to affect all the release versions, so I'm not sure whether it's a blocker to 1.5.

This is a release blocker and, thus, I have to cancel the RC 3. I'll prepare a new RC once the problem has been fixed. Thanks to all for testing the release candidate!  https://issues.apache.org/jira/browse/FLINK-9381?filter=12327438 Cheers, Till On Tue, May 15, 2018 at 5:32 PM, Till Rohrmann <trohrm...@apache.org> wrote: Hi everyone, Please review and vote on the release candidate #3 for the version 1.5.0, as follows: [ ] +1, Approve the release [ ] -1, Do not approve the release (please provide specific comments) The complete staging area is available for your review, which includes: * JIRA release notes , * the official Apache source release and binary convenience releases to be deployed to dist.apache.org , which are signed with the key with fingerprint 1F302569A96CFFD5 , * all artifacts to be deployed to the Maven Central Repository , * source code tag "release-1.5.0-rc3" , Please use this document for coordinating testing efforts:  The vote will be open for at least 72 hours.
