-------------------------------------
Summary: Improve CoreAdmin STATUS request response time by
allowing user to omit the Index info
Key: SOLR-4302
URL: https://issues.apache.org/jira/browse/SOLR-4302
Project: Solr
Issue Type: Improvement
Components: multicore
Affects Versions: 4.0, 4.1, 5.0
Reporter: Shahar Davidson
Priority: Minor
In large multicore environments (hundreds+ of cores), the STATUS request may
take a fair amount of time.
It seems that the majority of time is spent retrieving the index related info.
The suggested improvement allows the user to specify a parameter (indexInfo)
that if 'false' then index related info (such as segmentCount, sizeInBytes,
numDocs, etc.) will not be retrieved. By default, the indexInfo will be 'true'
(to maintain existing STATUS request behavior).
For example, when tested on a given machine with 380+ solr cores, the full
STATUS request took 800ms-900ms, whereas using indexInfo=false returned results
in about 1ms-4ms.
