You have a 12G heap for a 200MB index? Can you just try changing Xmx to, like, 1g ? On Tue, Oct 6, 2020 at 7:43 AM Karol Grzyb wrote: > > Hi, > > I'm involved in investigation of issue that involves huge GC overhead > that happens during performance tests on Solr Nodes. Solr version is > 6.1.

Re: Non Deterministic Results from /admin/luke

You may want to check the COLSTATUS collection command added in 8.1 (https://lucene.apache.org/solr/guide/8_6/collection-management.html#colstatus ). This reports much of the information returned by /admin/luke but

Java GC issue investigation

Hi, I'm involved in investigation of issue that involves huge GC overhead that happens during performance tests on Solr Nodes. Solr version is 6.1. Last test were done on staging env, and we run into problems for <100 requests/second. The size of the index itself is ~200MB ~ 50K docs Index has

Re: Java GC issue investigation

Hi Matthew, Thank you for the answer, I cannot reproduce the setup locally I'll try to convince them to reduce Xmx, I guess they will rather not agree to 1GB but something less than 12G for sure. And have some proper dev setup because for now we could only test prod or stage which are difficult

Re: Java GC issue investigation

12G is not that huge, it’s surprising that you’re seeing this problem. However, there are a couple of things to look at: 1> If you’re saying that you have 16G total physical memory and are allocating 12G to Solr, that’s an anti-pattern. See:

Re: Java GC issue investigation

Your index is so small that it should easily get cached into OS memory as it is accessed. Having a too-big heap is a known problem situation. https://cwiki.apache.org/confluence/display/SOLR/SolrPerformanceProblems#SolrPerformanceProblems-HowmuchheapspacedoIneed? On Tue, Oct 6, 2020 at 9:44 AM

Re: Order of applying tokens/filter

Synonyms only need to be done once. Generally, expand synonyms at index time only. Also, consider the StandardTokeniizer. It is a bit smarter and that can be useful. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Oct 5, 2020, at 9:08 PM,

timeAllowed default value

Hi everyone, What is the default value for timeAllowed to make it behave as if it is not set? Is it "-1" or some other number? Rather than writing my code to include or not include timeAllowed in the query parameter, I rather have it be part of my query all the time and only change the value if

Re: Using streaming expressions with shards filter

There is a parameter in streaming expressions for this but it is not available for use in every stream source. The search expression should honor it though. If you pass the .shard=shard1,shard2,shard3... The search stream will honor this. This work was originally done for supporting
