Subject [Discussion] SQL+Streaming/JDBC as one of the unified interfaces
Date Fri, 10 Nov 2017 11:49:17 GMT

I've been working lately on Apache Calcite SQL/JDBC adapter for Apache
Geode [1].

Adapter's current implementation act as a plain Geode client (using the
public API/OQL interfaces) trying to push down to Geode OQL as many
relational expressions as it can. Relational expressions not supported by
OQL are executed by the adapter itself.

While this approach has its advantages and disadvantages, which I will try
to address at my Geode Summit talk [2] I would like to ask two question:

1. Would you be interested to have the adapter as part of Geode's code

2. I am aware (an experienced it myself) the SQLFire story. But given that
OQL features are expanding (aggregations are are already supported) and
that tools like Calcite offer proper logical/physical (cost based) planer
and SQL extensions such as SQL streaming, would it be useful to discuss
what novel approaches for using SQL/JDBC with Geode are possible?
