Joel Bernstein created SOLR-9943:
------------------------------------
Summary: Add shards Streaming Expression
Key: SOLR-9943
URL: https://issues.apache.org/jira/browse/SOLR-9943
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Joel Bernstein
The shards() streaming expression is a stream source that emits a set of shards
to be searched. All the Solr stream sources will accept this expression and use
it instead of *collection* name to contact the shards if it's passed in.
A base ShardsStream implementation that simply takes a list of shards as will
be mapped to the shards() expression.
Users can override the shards expression with custom functionality by extending
the ShardsStream and mapping the custom implementation in the solrconfig.
This is a generic solution for people who don't use SolrCloud but want to use
Streaming and Parallel SQL and JDBC.
