Varun Thacker commented on SOLR-12057: -------------------------------------- Hi Amrit, Some feedback on CdcrUpdateProcessor * Can we add some javadocs as to what this update processor wants to achieve? * Do we still need to override versionAdd / versionDelete versionDeleteByQuery ? * It would be nice to add some basic docs to the {{filterParams}} method to indicate what it's trying to filter etc. On CdcrReplicaTypesTest * {{//.withProperty("solr.directoryFactory", "solr.StandardDirectoryFactory")}} - Can we remove this comment? * Is {{testTlogReplica}} meant to only have tlog replicas? The create collection uses a combination of nrtReplicas and tlogReplicas so I'm trying to understand the motivation here * "Not really, we can remove this safely, from, all tests; 2 sec sleep is for loading the Cdcr components and avoiding potentially few retries." - You mentioned this but the patch still has a 2s delay * {{int batchSize = (TEST_NIGHTLY ? 100 : 10);}} - does batchSize represent numBatches? 100 seems to be the batch size in the inner loop >From a design perspective : Given the improvements you've made with the patch , are we in a position to roll up this block from CdcrUpdateProcessor into DistributedUpdateProcessor ? If yes then we would get CDCR to work even without them having to add an UpdateProcessor ? We coiuld keep CdcrUpdateProcessor as is for backward compat but remove references of it from the docs {code:java} if (params.get(CDCR_UPDATE) != null) { result.set(CDCR_UPDATE, ""); result.set(CommonParams.VERSION_FIELD, params.get(CommonParams.VERSION_FIELD)); }{code} > CDCR does not replicate to Collections with TLOG Replicas > --------------------------------------------------------- > > Key: SOLR-12057 > URL: https://issues.apache.org/jira/browse/SOLR-12057 > Project: Solr > Issue Type: Bug > Security Level: Public(Default Security Level.
