Gian,
For the presto-sql version of Druid connector, for V1, we decided to pursue
the JDBC route. You can follow along on the progress here -

My colleague, Parth (cc'ed as well) is working on implementing Druid
aggregation push down including

Thank you, Mainak.
Hi Gian,
Glad to see you are interested in Presto Druid connector.
My colleague, @Hao Luo @Beinan Wang
and
me, together, implemented the Presto Druid connector in PrestoDB:

Our implementation includes:

Hello Gian,
We are currently testing the (other) Presto Druid connector at our end. It has
aggregation push down support. Adding Zhenxiao to this thread since he is the
primary developer of the connector. He can provide the kind of details you are
looking for.
Thanks,
Mainak

I wrote the Druid connector that reads directly from deep storage(the one
you found in prestodb). It understands the segment file format and read
only the data needed for the query. I think its possible to have
aggregation pushdown(and even more possibilities with other complex

I was thinking of exploring ideas like pushing down aggregations, enabling
Presto to query directly from deep storage (in cases where there aren't any
interesting things to push down, this may be more efficient than querying
Druid servers), enabling translation from Druid's SQL dialect to Presto's
Hi Gian,
I contributed the jdbc based presto-druid connector in prestosql which went
out in release 337
https://prestosql.io/docs/current/release/release-337.html. The v1 version
of the connector doesn’t support aggregate push down yet. It is being
actively worked on and we expect it to be
Hey Druids,
I was wondering, is anyone on this list using Druid + Presto together? If
so, what does your architecture look like and which edition / flavor of
Presto and Druid connector are you using? What's your experience been like?
I'm asking since I'm starting to think about whether it makes
