Varun Thacker commented on SOLR-11003: -------------------------------------- Hi Amrit, Patch is looking good! Let's add some code comments in CDCRTransactionLog and CDCRReplicator. For example, this change in CDCRTransactionLog is confusing till you look at CDCRReplicator#isTargetCluster {code} if (cmd.getReq().getParamString().contains(CdcrUpdateProcessor.CDCR_UPDATE)) { codec.writeTag(JavaBinCodec.ARR, 6); } else { codec.writeTag(JavaBinCodec.ARR, 5); } {code} The test has adds, deleteByid and deleteByQuery. Can we also test for in place updates ( I didn't see a anything triggering that code path ) Also it wouldn't hurt to add atomic updates to the test. > Enabling bi-directional CDCR active-active clusters > --------------------------------------------------- > > Key: SOLR-11003 > URL: https://issues.apache.org/jira/browse/SOLR-11003 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level.
