Hope you're doing good. I am trying to configure NRT - Indexing in my project. For this reason, I have configured *autoSoftCommit* to execute every second and *autoCommit* to execute every 5 minutes. Everything works as expected on the dev and test server. But on the production server, there are more than 6 million documents indexed in Solr, so whenever a new document is indexed it takes 2-3 minutes before appearing in the search despite the setting I have described above. Since the target is to develop a real-time system, this delay of 2-3 minutes is not acceptable. How can I reduce this time window?
Setting autoSoftCommit with a max time of 1000 (one second) does not mean you will see changes within one second. It means that one second after indexing begins, Solr will start a soft commit operation. That commit operation must fully complete and the new searcher must come online before changes are visible. Those steps may take much longer than one second, which seems to be happening on your system.
With the information available, I cannot tell you why your commits are taking so long. One of the most common reasons for poor Solr performance is a lack of free memory on the system for caching purposes.
Thanks, Shawn
