Hi there,

in fact, aggregation query builder is already scheduled to be removed in
version 2.23 and will be replaced by program indicators. Admittedly there
are a few cases where persisted aggregate event data could be useful,
however we think that generating the aggregate values "on the fly" will
provide more flexibility and be less of a load on the server by avoiding
large, nightly batch jobs.

The current aggregation query builder was not up to scratch and could have
unpredictable behavior. At some point, we might use the program indicator
engine as basis for supporting persistence of aggregated event data, but
that is not top priority currently.

We encourage you to try out the program indicators and provide feedback to
the dev team.

regards,

Lars
