Hi

I would really appreciate it if any of you can share your insights with
such a use case.

Thanks much

 Hi

  In Solrcloud (4.6.1) every time 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 has the risk of potentially
 bringing down the collection itself (or cause it to be unstable)

 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 (which
 can be changed on the fly). This can help with dynamically changing
 properties without core reloads.

 Is this a common use case and can be achieved without core reloads?

 Kindly advise,

 Nitin
