Joel Bernstein updated SOLR-8588: --------------------------------- Attachment: SOLR-8588.patch Patch with first set of working tests. > 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 > Assignee: Joel Bernstein > Attachments: SOLR-8588.patch, SOLR-8588.patch > > > The TopicStream is a *publish/subscribe messaging service* built on top of > SolrCloud. The TopicStream returns all *new* documents for a specific query. > Version numbers will be used as checkpoints for Topics to ensure single > delivery of each document. When combined with the DaemonStream (SOLR-8550), > Topics can provide continuous streaming. Sample syntax: > {code} > topic(checkpointCollection, dataCollection, id="topicA", q="awesome stuff" > checkpointEvery="1000") > {code} > The checkpoint collection will be used to persist the topic checkpoints. > Example combined with the DaemonStream: > {code} > daemon(topic(...)...) > {code} > When combined with SOLR-7739 this allows for messaging based on *machine > learned* classifications. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
