Subject Re: 7.3.1: Query of death - all nodes ran out of memory and had to be shut down
Date Tue, 21 Aug 2018 11:25:42 GMT
The solution is to move to cursors, but you may as a safety net try to apply the RequestSanitizerComponent to disallow large offsets, see https://github.com/cominvent/request-sanitizer-component <https://github.com/cominvent/request-sanitizer-component>

It's difficult to say for someone else, but we identified deep paging as the definite reason for running out of memory or at least grinding to semi-halt because of long stop-the-world garbage collection pauses in an application running on a similar SolrCloud. You can often get away without issues as long as you only have a single shard, but for the reason Erick mentioned deep paging in a sharded index is a heavy operation.
