Re: CASSANDRA-20490 Question about broken forced ephemeral snapshots during repair

>So if we moved to determanisticId for both branches of if / else and remove force, we should be good? RepairJobDesc#deterministicId is basically unique? The challenge with using RepairJobDesc#deterministicId in the SNAPSHOT_MSG is that it will create N snapshots for N token-splits for a table. How

Re: Test Strategy for Cassandra

Thanks Josh for your insights. That distinction between unit tests and dtests—especially in relation to intra-node vs. multi-node behavior—really helps clarify things. I’ll take another look at the patch and work on writing appropriate test cases accordingly, potentially shifting towards an in-jvm

Re: Facets | Cassandra v5.0

Facets as supported by ES, Solr, etc. (i.e. count aggregates on groups w/ global queries) are not on the roadmap (if we want to call it that) for SAI. One thing we haven't explored much yet is what utility we might get out of combining SAI (for filtering) w/ Cassandra's existing partition-restrict

Re: CASSANDRA-20490 Question about broken forced ephemeral snapshots during repair

That true / false for "force" argument seems to be purely derived from whether it is global repair (force set to false) or not (set to true). https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/repair/RepairMessageVerbHandler.java#L185-L192 On Tue, May 13, 2025 at 5:25 PM

Re: CASSANDRA-20490 Question about broken forced ephemeral snapshots during repair

That method can be backported even if it’s just for this single case. For the vtable I needed something more friendly so made this for that. It’s also used for dedup logic in repair retry works.  I didn’t look closely, what sets force to be true or false? I assumed this was the force flag in repair

Re: Test Strategy for Cassandra

Given the title on 20291: "Batch queries timeout when private IP of a node fails in multi-dc Cassandra setup", this seems like a prime candidate for an in-jvm dtest. The way I think about it: if I need to exercise intra-node communication or functionality to confirm that something operates the w

Hi Maxim, I took yet another look after my initial review some time ago and I still do not see any issues with it. I appreciate that by default it behaves exactly the same way as before and one has to just flip a switch (env property / system property) to start to use another layout. Arguments /

Test Strategy for Cassandra

Hi everyone I have a question regarding test strategy in Cassandra. Under what circumstances is a dtest preferred over a unit test? Specifically, what criteria should guide the decision to write a dtest instead of a unit test? I’ve prepared a patch for CASSANDRA-20291, but I’m encountering some c
