Solr 8.3.1 longer query latency over 6.4.2

2020-08-19 Thread Elaine Cario
Hi Solr experts, We're in the process of upgrading SolrCloud from 6.4.2 to 8.3.1, and our performance testing is consistently showing search latencies are measurably higher in 8.3.1, for certain kinds of queries it may be as much as 200 ms higher on average. We've seen this now in 2 different env

We're preparing to upgrade from Solr 6.4.2 to Solr 7.6.0, and found an inconsistency in scoring. It appears that term boosts in the query are not applied in Solr 7. The query itself against both versions is identical (removed un-important params): ("one"^1) OR ("two"^2) OR ("three"^3) edismax max

CDCR configuration in solrconfig

2017-12-18 Thread Elaine Cario
We've recently been exploring options for disaster recovery, and took a look at CDCR for our SolrCloud(s). It seems to meet our needs, but we've stumbled into a couple of issues with configuration. The first issue is that currently CDCR is configured as a request handler in solrconfig, but becaus

Implications of putting a load balancer in front of Zookeeper

2017-07-06 Thread Elaine Cario
Hi All, Normally, when we set up a SolrCloud environment, we put a load balancer in front of the Solr nodes, which we use for sending queries (HttpSolrServer), and use CloudSolrServer (with the IPs for the zookeeper ensemble nodes) for sending indexing operations. Recently we embarked on a projec

2017-03-29 Thread Elaine Cario
I need some clarity on atomic vs in-place updates. For atomic I understand that all fields need to be stored, either explicitly or through docValues, since the entire document is re-indexed. For in-place updates, the documentation states that only the fields being modified are updated, but does t

Oh, never mind. Apparently staring at logs has led to blindness...I do see the "master" query with the full elapsed time and hit count, and indeed, there is a parameter "_" with some tracking number which links all the queries together. On Thu, Sep 22, 2016 at 7:32 PM,

SolrCloud query logs, change from 4.10 to 5.5

We're in the process of upgrading from SolrCloud 4.10 to 5.5, and we noticed a change in how distributed queries get logged. In Solr 4.10 we noted that the original node receiving the query logged the query with a full hit count and elapsed time for the entire query, using the original request han

Anil, I've seen situations where if there was a problem with a specific query, and every shard responds with the same error, the actual exception gets hidden by a "No live SolrServers..." exception. We originally saw this with wildcard queries (when every shard reported a "too many expansions...

You may be bumping into this bug: https://issues.apache.org/jira/browse/SOLR-7951. Can you try a simple query (no grouping) and see if Solr responds? On Tue, Feb 23, 2016 at 11:57 AM, Mugeesh Husain wrote: > Yes, all of the shards in a live state. I guess may be there will be > docvalues type N
