updates from the leader just like a PULL replica and does not perform soft-commits. The difference is that the non-leader TLOG replica also captures updates in its TLOG, so that it is a candidate to replace the current leader if it is lost. Thanks, Wei On Tue, Aug 27, 2024 at 1:54 PM Kevin Liang

Hi Saksham, You don't have to perform full indexing for the merge policy setting change. For the ideal settings, it depends on what you are trying to optimize. Generally more merges and smaller number of segments help to improved search performance. Thanks, Wei On Thu, May 18, 2023

Hi Shawn, Do you see ZGC having better query performance than G1? We are migrating from Solr 8 / JDK 11/ G1 to Solr 9 with JDK 17 / G1. Also are there any notable performance changes from 9.0.0 to the latest 9.1.1? Thanks, Wei On Mon, Feb 6, 2023 at 1:34 PM Shawn Heisey wrote: > On 2/6

Maximum number of shards and nodes in solr cloud

Hi team, Is there a practical limit on the number of shards and nodes in a solr cloud? We need to scale up the solr cloud and wonder if there is concern when increasing to a couple of hundred shards and several thousand nodes in a single cloud. Any suggestions? Thanks, Wei
