----------------------------------
Summary: Updating Solr-Core Properties on the Fly to avoid
core/collection reloads
Key: SOLR-7479
URL: https://issues.apache.org/jira/browse/SOLR-7479
Project: Solr
Issue Type: Improvement
Components: SolrCloud
Affects Versions: 4.6.1
Environment: Any Platform
Reporter: Nitin Sharma
Currently everytime a property/value is changed in solrcore.properties file, a
core/collection reload is needed to pick up the new values.
Core/Collection reloads for large collections (example 100 shards) is very
expensive (performance wise) and can pose a threat to the collection stability
(sometimes the reload fails since the timeout is only 60 seconds).For a RT
serving infrastructure, this does not help
Would adding a Real Time config api (map) inside solrcloud help? Every solr
core can pick up the core specific configs from this Shared Map. This can help
with dynamically changing properties without core reloads.
If there is a better solution than that, please let me know
