How can I improve my Solr performance?
5 Ways to Optimize Sitecore Solr Search Performance
- Set the autoSoftCommit feature to 2 minutes.
- Set the autoCommit feature to 5 minutes.
- Use autowarmCount = 0 for All Cache Settings.
- Set maxRamMB to 200.
- Use the Default Values of True for Lazy Fields and Sorted Query.
What does Solr optimize do?
Optimize: This is similar to a defrag command on a hard drive. It will reorganize the index into segments (increasing search speed) and remove any deleted (replaced) documents.
How much RAM does Solr need?
As rule of thumb, the minimum size of direct memory recommended is 8G for a production system if docValues is not used in schema and 12-16G if docValues is used. A related configuration is block cache slab count (Cloudera Manager->Solr configuration->slab count) which needs to match direct memory size.
How can I know my Solr URL?
You can see that Solr is running by launching the Solr Admin UI in your web browser: http://localhost:8983/solr/. This is the main starting point for administering Solr.
What kind of data can a Solr index accept?
By adding content to an index, we make it searchable by Solr. A Solr index can accept data from many different sources, including XML files, comma-separated value (CSV) files, data extracted from tables in a database, and files in common file formats such as Microsoft Word or PDF.
How does scaling in Solr start and end?
In the Scaling Progression diagram, you can get a better visual idea of how this progression works. It starts with a single machine serving all queries and handling all index updates. Next there is the master/slave configuration, where the master handles all updates and replicates all index changes to the slaves.
What kind of architecture does Solr work on?
Multiple cores can run on a single node. See also SolrCloud. 1. Solr works on a non master-slave architecture, every solr node is master of its own. Solr nodes uses Zookeper to learn about the state of the cluster.
How are documents organized in a Solr cluster?
See also SolrCloud. In Solr, one or more Documents grouped together in a single logical index using a single configuration and Schema. In SolrCloud a collection may be divided up into multiple logical shards, which may in turn be distributed across many nodes, or in a Single node Solr installation, a collection may be a single Core.
