See information below on travel assistance for ApacheCon 2018. It would be
great to see some representation for Calcite. I'm hoping to attend myself,
although not yet confirmed.

I want to build a RelNode tree with different conventions on different RelNodes
(for example: in the following select query "select * from t1,t2", t1 is a
table from Oracle and t2 is a table from SqlServer).
I'm confused whether i should be using a single SchemaPlus to hold table

We are considering using Calcite to perform cost-based query optimization
in our project.
Specifically, we can already generate some SQL queries expressed in some
relational algebra expression through our API, and we want to optimize the
generated expressions using Calcite.
We have a cost

I have re-checked more carefully, the issue has indeed been fixed, sorry

while executing this query Calcite tries to cast the subquery (RexSubQuery)
to a local reference (RexLocalRef), resulting in a ClassCastException.
Here is the query:
> *select **
> *from (values (1, 'a'), (2, 'b'), (3, 'b'), (4, 'c'), (2, 'c')) as t(x, y)*
> *where exists (*

I want to use calcite adapter with elastic search and java. But i haven't idea
how to use calcite elastic search adapter could you please let us know how to
use calcite adapter with elastic search and java.
Thanks in advance for your co operation
Thanks & Regards
It sounds like a good fit. Parse the SQL, translate to relational algebra,
apply some query transformation rules on the algebra.
If you have a few simple transformations in mind, you may be able to achieve it
without a cost model. Or, as you propose, a simple model based on cardinality.
I exclude that because in that branch I have got the two mentioned in the
JIRA ticket (+ ~28 new tests) passing, and this one failing.
Also the exception is different, in the ticket it was an assertion on the
plan/resultset failing, while in this new case it is the code compilation

while preparing some additional unit tests for the spark adapter (
https://github.com/asolimando/calcite/tree/SPARK-TESTS) I have stumbled
upon the issue several times.
This is the list of the tests that in my opinion should be succeeding but
are failing because of an invocation of *copy*
Does anyone have a docker container with
Jekyll configured for Github site generation like described in site/
readme.md and published?
If not, would it make sense to build few containers and publish them
official on Dockerhub for various development and testing tasks?
