Re: Urgent- General Question about document Indexing frequency in solr

Manisha, The most general recommendation around commits is to not explicitly commit after every update. There are settings that will let Solr automatically commit after some threshold is met, and by delegating commits to that mechanism you can generally ingest faster. See this blog post that

Just go ahead and optimize/forceMerge, but do _not_ optimize to one segment. Or you can expungeDeletes, that will rewrite all segments with more than 10% deleted docs. As of Solr 7.5, these operations respect the 5G limit. See: https://lucidworks.com/post/solr-and-optimizing-your-index-take-ii/
