Hi All,
When running a HepOptimizer on top of a RelNode which has a subquery
embedded in it, The Optimizer does not take the RelNode representing the
subquery up for optimization.
Is this by design, what's the correct way for the Subquery RelNode to be
picked up for Optimization?
If this is a

Hi All,
When creating a RelNode for a Query with a DISTINCT keyword in it, I use
the relBuilder.distinct() api to apply distinct.
It creates a LogicalAggregate with all the Fields of the LogicalProject as
the GroupKey.
This is a problem when one of those projections is a windowing function

Hi,
When creating a TableModify(Update), I see correlated variables are used to
encapsulate the right side of SET expressions.
I was wondering what is the purpose of creating correlated variable
references.
On its face value, it seems to create stand-alone expressions, column
references are

Okay, will try and come up with a PR then.

Hi,
Unparsing of SqlWindow related to SqlRankFunction & SqlLeadLagFunction type
of SQL Operators should consider whether the Boundary Specifications should
be printed or not(where Framing is not allowed!)
For Instance,
*SELECT employee_id, ROW_NUMBER() OVER (PARTITION BY department_id ORDER BY
obably “ORDER BY ” is the best solution on dialects

Hi All,
I am trying to convert a Simple RelNode to SQL Text with Hive as Dialect
using RelToSqlConverter.
Problem is if the Order By Key is a Projection which was Aliased, the
Output query contains the original column name instead of the Alias, which
is not allowed in Hive as valid Order By keys
Hi All,
I am using the VolcanoPlanner(with Default Rules) to optimize a RelNode
which has a Join as below:-
LogicalJoin(condition=[AND(AND(AND(=($1, $46), =(CAST($11):FLOAT NOT NULL,
$47)), <>($46, -999)), <>($47, -999))], joinType=[left])
LogicalTableScan(table=[[defaultschema,
