Joel Bernstein updated SOLR-8588:
---------------------------------
Summary: Add TopicStream to the streaming API (was: Add TopicStream to
streaming API)
> Add TopicStream to the streaming API
> ------------------------------------
>
> Key: SOLR-8588
> URL: https://issues.apache.org/jira/browse/SOLR-8588
> Project: Solr
> Issue Type: New Feature
> Reporter: Joel Bernstein
>
> Topics are similar to Alerts (SOLR-8577) in that they return only new
> content. But Topics return *all* new documents for a query, where Alerts
> return the top N results. So where Alerts are designed to notify of very
> specific new content, Topics are primarily a syndication tool.
> When combined with DaemonStream (SOLR-8550), Topics can provide continuous
> streaming. Sample syntax:
> {code}
> topic(checkpointCollection, dataCollection, q="awesome stuff")
> {code}
> The checkpoint collection will be used to persist the topic checkpoints.
> Example combined with the DaemonStream:
> {code}
> daemon(topic(...)...)
> {code}
