looks like the test is failing: https://ci-beam.apache.org/job/beam_PreCommit_Java_Commit/23003/testReport/junit/org.apache.beam.sdk.io.cassandra/CassandraIOTest/testWrapAroundRingRanges/

@pabloem I fixed a query. Looks ok now. Could you or maybe @damccorm help out with a review if possible? Thanks.

@brucearctor thanks, looks like the unrelated, flaky test now passed. What are the next steps to getting this merged?

[brucearctor]

I haven't worked with this component [ cassandraIO ] -- so hoping either for more context, or for someone that's worked closer with it to step in.

Is there an associated issue [jira/github] that this relates to/addresses. That would be a start to provide context on what this is/why - which is also useful more generally for anyone looking through the code/changes/history.

Ex, from the PR template: Mention the appropriate issue in your description (for example: "addresses https://github.com/apache/beam/pull/123), if applicable. This will automatically add a link to the pull request in the issue. If you would like the issue to automatically close on merging the pull request, comment "fixes #" instead.

@brucearctor thanks. I had "fixing" instead of "fixes" so I guess it didn't auto pick up the issue it addresses, but at the top you should see the issue it's for: #21715

@KriKroff you wrote --> https://github.com/KriKroff/beam-cassandraio-bug

Can you take a look and verify this PR addresses this issue?

In principle LGTM, but hoping for a set of eyes more familiar with the component/issue.

[vmarquez]

Thanks for taking a look, really appreciate it @brucearctor

[pabloem]

so sorry. I can't look at this.

LGTM. The added unit test passed, and verified it fails on current master with java.lang.AssertionError: counting/Flatten.PCollections.out: expected:<100> but was:<99>, which means this change fixed the problem

@Abacn Thank you so much for the review! :)
