Hello, I load data from csv to solr via UpdateCSV. There are about 50M documents with 10 columns in each document. The index size is about 15GB and I am using a 3 node distributed solr cluster.
While loading the data the disk IO goes to 100%. if the load balancer in front of solr hits the machine which is doing the processing then the request times out. But in general, requests to all the machines become slow. I have attached a screenshot of the diskI/O and CPU usage. Is there a fix in solr which can possibly throttle the load or maybe its due to MergePolicy? How can I debug solr to get the exact cause? -- Thanks, -Utkarsh
