-----------------------------------------
Summary: indexing delay due to zookeeper election
Key: SOLR-5577
URL: https://issues.apache.org/jira/browse/SOLR-5577
Project: Solr
Issue Type: Bug
Reporter: Christine Poerschke
The behaviour we observed was that a zookeeper election took about 2s plus 1.5s
for reading the zoo_data snapshot. During this time solr tried to establish
connections to any zookeeper in the ensemble but only succeeded once a leader
was elected *and* that leader was done reading the snapshot. Solr document
updates were slowed down during this time window.
Is this expected to happen during and shortly after elections, that is
zookeeper closing existing connections, rejecting new connections and thus
stalling solr updates?
Other than avoiding zookeeper elections, are there ways of reducing their
impact on solr?
