Summary: Configuring Solr Cloud to use Shared Storage
Key: SOLR-14213
URL: https://issues.apache.org/jira/browse/SOLR-14213
Project: Solr
Issue Type: Sub-task
Components: SolrCloud
Reporter: Andy Vuong
Clients can currently create shared collections by sending a collection admin
command such as
*_solr/admin/collections?action=CREATE&name=gettingstarted&sharedIndex=true&numShards=1_*
There are a set of shared storage specific classes such as SharedStorageManager
that get initialized on startup when the CoreContainer loads. There are also
components that are lazily loaded when shared storage functionality is needed.
This was initially written this way because a Solr Cloud cluster could spin up
and not used shared collections in which case shared store components wouldn’t
need to be loaded. There is also no support for configuring Solr Cloud to use
shared storage via config files. Lazy loading leads to some poor code and
initialization flow that should be revisited.
This JIRA is for designing the configuration of Solr Cloud to use shared
storage and initializing shared storage components based on this.
