Joel Bernstein updated SOLR-10566: ---------------------------------- Attachment: SOLR-10566.patch Initial implementation tests to follow. > Add timeseries Streaming Expression > ----------------------------------- > > Key: SOLR-10566 > URL: https://issues.apache.org/jira/browse/SOLR-10566 > Project: Solr > Issue Type: New Feature > Security Level: Public(Default Security Level. Issues are Public) > Reporter: Joel Bernstein > Attachments: SOLR-10566.patch > > > This ticket is to add specific time series support to streaming expressions. > Under the covers the timeseries expression will use the json facet API. > sample syntax: > {code} > timeseries(collection, > q="*:*", > start = "2011-04-01T01:00:00.000Z", > end = "2016-04-01T01:00:00.000Z", > gap = "+1MONTH", > count(*), > sum(price)) > {code} > This goes nicely with SOLR-10559. The idea is to support expressions that > cross-correlate and regress time series data. > {code} > let(cell(timeseriesA, timeseries(...)), > cell(timeSeriesB, timeseries(...)), > list(cell(a, get(timeseriesA)), > cell(b, get(timeseriesB)), > cell(stats, regres(col(timeseriesA, count), col(timeseriesB, > count))))) > {code} -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
