[jira] [Commented] (SOLR-14673) Add CLI for Streaming Expressions
[ https://issues.apache.org/jira/browse/SOLR-14673?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17849458#comment-17849458 ] Eric Pugh commented on SOLR-14673: -- I've opened up a draft PR to bring the patch file up to date and use SolrCLI. In my mind, I was thinking a command might look like: bin/solr stream echo(hello) and you would run that streaming expression. How ever, maybe what the patch expects is a bin/solr stream myexpression.expr and the myexpression.expr would contain the text "echo(hello)" ?? > Add CLI for Streaming Expressions > - > > Key: SOLR-14673 > URL: https://issues.apache.org/jira/browse/SOLR-14673 > Project: Solr > Issue Type: New Feature > Components: streaming expressions >Reporter: Joel Bernstein >Assignee: Eric Pugh >Priority: Major > Attachments: SOLR-14673.patch, SOLR-14673.patch, SOLR-14673.patch, > SOLR-14673.patch, SOLR-14673.patch > > Time Spent: 10m > Remaining Estimate: 0h > > This ticket will provide a simple CLI that will run a Streaming Expression > from the command line and return the results as a delimited result set.
