Hi All,
Looking for a bit of support here. When we soft commit (every 10 minutes), we
get a latency spike that means response times for solr are loosely double, as
you can see in this screenshot:
[cid:ed9fa791-0776-43fc-8f22-d8a568f5c084]
These do correlate to GC spikes (albeit not particularly bad):
[cid:36724c12-ef9a-4764-b132-86794824bd61]
But don't really correlate to disk or cpu/ram stress:
[cid:6e0306e4-ed51-459c-b55f-d0e1175fcc34]
They do correlate to filterCache warmup, which seem to take between 10s and 30s:
[cid:7b8acb40-fa7b-4653-9214-6b2010b3529d]
We don't have any other caches enabled, due to the high level of cardinality of
the queries.
The spikes are specifically on /select
[cid:19b70fb5-9894-4b30-a6a3-459e0e58f532]
We have the following autowarm configuration for the filterCache:
<filterCache class="solr.FastLRUCache"
size="8192"
initialSize="8192"
cleanupThread="true"
autowarmCount="900"/>
And some suitable queries in our newSearcher warmup config.
I'm at a lot at what else to do to try and minimise these spikes. Does anyone
have any ideas?
Thanks
