We have a cluster that is running out of heap during indexing. Our older cluster does not have this problem. Both clusters have 8 shards and 3 replica sets, for a total of 24 hosts. Both use the same G1GC settings. Both have the same indexing feed of 57 million documents.
Old cluster: Solr 6.6.2 11 GB heap Oracle Corporation OpenJDK 64-Bit Server VM 1.8.0_131 25.131-b11 New cluster: Solr 8.7.0 16 GB heap Amazon.com Inc. OpenJDK 64-Bit Server VM 11.0.10 11.0.10+9-LTS Cache sizes on the new cluster are pretty standard, filter and query result caches are 512, document cache is 2048. Documents aren’t huge, maybe average size a few kbytes. They are homework problems. Any ideas? The 6.6.2 cluster has been running for a few years with no indexing problems. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog)
