Just wanted to close the loop on this in case anyone stumbled upon the same
issue.
After upgrading to version 1.3.2 which had the performance increase
stemming from https://github.com/elasticsearch/elasticsearch/pull/5846, we
were able to see a dramatic decrease in parent/child query latency. W
Hey Clinton,
Thanks for the heads up on what's on the horizon. That definitely sounds
like a drastic improvement. That being said, my fear here is that even with
that improvement, this data model (parent/child) doesn't seem to that
performant with a moderate amount of documents. In order for us
Something else to note: parent-child now uses global ordinals to make
queries 3x faster than they were previously, but global ordinals need to be
rebuilt after the index has refreshed (assuming some data has changed).
Currently there is no way to refresh p/c global ordinals "eagerly" (ie
during th
Hi Adrien,
Thanks for reaching out.
We actually were exited to see the performance improvements stated in the
1.2.0 release notes so we upgraded to 1.3.2. We saw some performance
improvement but it wasn't orders of magnitude and queries are still running
very slow.
We also tried your suggesti
Hi Mark,
Given that you had 1 replica in your first setup, it could take several
queries to warm up the field data cache completely, does the query still
take 16 seconds to run if you run it eg. 10 times? (3 should be enough, but
just to be sure)
Does it change anything if you query elasticsearch
I wanted to update the list with an interesting piece of information. We
found that when we took one of our two data nodes out of the cluster,
leaving just one data node with no replicas, the query performance
increased dramatically. The queries are now returning in <100ms on
subsequent executi
We are experiencing slow parent/child queries even when we run the query a
second time and I wanted to know if this is just the limit of this feature
within ElasticSearch. According to the ES Docs
