Hello, I've been trying out the shards.preference=replica.type:PULL as a parameter appended onto queries, as well as trying out including it in the search request handler. For context, we have a collection that is 2 shards, 2 TLOGs per shard, and n number of PULLs (can change depending on if we wish to add more replicas during higher periods of traffic). This is being tested in Solr 8.8.2.
In an effort to verify that the queries were being handled by only the PULL replicas, I've been looking at our Solr request logs, expecting to see only pull replica types handling our queries. Yet, I am seeing a number of "replica": "x:collectionname_shardx_replica_tx" included in the request logs, which seems to insinuate that the TLOG replicas are still serving queries. I have two questions: 1.) am I right in assuming that setting the replica.type should be exclusively sending requests to PULL replicas? 2.) If that is true, why would I still be seeing TLOG types on the Solr request logs? Is there some type of routing done behind-the-scenes that is not visible in the request logs? Thank you in advance for any guidance you can provide. [cid:image001.png@01D84B2C.876A3B40] Olivia Crusoe Software Engineer Lead - Search
