Hi all,
in the last weeks I worked on Integrating the Apache IoTDB Project with Calcite.
This covers two possible scenarios. One, to use Apache IoTDB as an Adapter in
Apache Calcite (like MongoDB, Cassandra, et al) and on the other hand we are
looking at using Calcites Query Optimizer to
the planner?
Regards,
Vladimir.

Hi,
I agree with Julians view. And I also agree with initially starting with
Avatica as separate TLP but not as a separate PMC (there are multiple Examples
of PMCs that govern multiple Projects, like pointed out from Julian).

Hi,
this is a good point Julian. So an implementation should consider a re-planning
(possibly triggered by a quick recheck of cost function with the given Literal
values). But this should not be a general issue with the approach, or?

Hi Shashwat,
Calcite does this by a Call to the "AS" Operator (basically value as v is just
syntactic sugar for AS(value, v)).
So you need to create a call node (SqlCall) with the AS Operator
(SqlStdOperatorTable.AS) and as operands you node and an SqlIdentifier for the
Alias.
But your
