----------------------------------
Summary: LTR queries producing out of memory issues
Key: SOLR-17018
URL: https://issues.apache.org/jira/browse/SOLR-17018
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: contrib - LTR, ltr
Affects Versions: 9.1.1
Reporter: rajanimaski
LTR queries are producing oom and looks like the issue is same as what is
described on this SOLR-5986. Because LTR component does not implement
`timeAllowed`, during peak traffic hours, when 80% of resources are in use, one
expensive LTR query that either has 10 or more terms or paginated with
start>=500 are leading to full heap usage, invoking full GC, reporting an oom.
Certain LTR queries are taking more than 15 seconds which seems like is the
issue, it is during this time interval the tenured(old generation) heap is
getting filled up as well.
