Solr Configuration Best Practices and Troubleshooting Tips : Support
Darla Baker Configuration Best Practices (Straying from these recommendations is the root cause of 90% of issues) Hardware Use SSDs if possible If using mechanical disks, setup at least 4 volumes with a set of dedicated heads for each: OS, commit log, SSTables, Solr data If using SSDs you can choose either RAID0 or JBOD Additional cores are helpful because it will increase query/indexing throughput Hardware/Cluster Sizing Create a CF with the proposed schema and configurations Load one thousand mock/sample records Extrapolate from those numbers the index size for the expected total record count Example If your index size is 1GB, and you expect one million records then your index size will be 1000GB. Your cluster must be large enough so that the total cluster memory is large enough to cache the total index size, and hot dataset, subtracting for the JVM heap and OS overhead. Assume 1GB of memory for the OS and 14 GB of memory for the JVM heap, or an overhead of 15GB.Read full article from Solr Configuration Best Practices and Troubleshooting Tips : Support
