Yes - I am wondering if solr will split segments when the config is updated to reduce the max segment size

The situation is we have a larger max segment size currently configured (let's say 10GB) and we want to update the config to reduce the max segment size (let's say 5GB). Will we need to reindex for that reduction to take effect? I have only seen code/explanations around merging (i.e. Joining two segments into larger segments) but never anything about segment splitting (which I imagine doesn't happen?) > > From: users@solr.apache.org At: 12/09/24 12:22:38 UTC-5:00To: users@solr.apache.org > Subject: Re: Merge Policy Max Segment Size + Reindexing > > As far as I know it does not require reindexing.
