--------------------------------
Summary: Aggregate queries
Key: OAK-862
URL: https://issues.apache.org/jira/browse/OAK-862
Project: Jackrabbit Oak
Issue Type: Improvement
Components: jcr
Reporter: sakshi arora
‘Group by’ query to get count(frequency) for each uid(could be a no. or
string). This will extend to 'group by' on multiple fields, with the usual
predicates ('where' - already available).
The use-case involves, frequency-based summary charts.
As charts are mostly frequency based, e.g. on duration, on category, on
date/month/time/year.
The data collection could range from live data to the daily scheduled
synchronization.
Required efficiency: Queries should be pretty fast, as usual location of these
charts is on dashboards (which are the home pages for most sites).
