Hi [~IhorHuzenko] and [~vvysotskyi],
I've updated the following doc sections with info for CROSS JOIN support:
* [https://drill.apache.org/docs/from-clause/#join-types] (I also included a
cross join example in the Examples section)
* [https://drill.apache.org/docs/select/#joins]
Please review the updates and let me know if I need to make any changes.
Thanks!

Igor Guzenko commented on DRILL-786:
Documentation note:
Due to it's nature cross joins can produce extremely large results, and we
don't recommend to use the feature if you don't know that results won't cause
out of memory errors. That's why cross joins are disabled by default, to allow
explicit cross join syntax you'll have to enable it by setting
_*planner.enable_nljoin_for_scalar_only*_ option to _*false*_. There is also
another limitation related to usage of aggregation function over cross join
relation. When input row count for aggregate function is bigger than value of
_*planner.slice_target*_ option then query can't be planned (because 2 phase
aggregation can't be created in such case), as a workaround you should set
*_planner.enable_multiphase_agg_* to _*false*_. This limitation will be active
until fix of https://issues.apache.org/jira/browse/DRILL-6839.

@ihuzenko sorry I missed responding to your earlier comment. Based on your
latest comment, I suppose we can merge this PR but explain the limitation of
the Cross Join in the documentation until
[DRILL-6839](https://issues.apache.org/jira/browse/DRILL-6839) is fixed.
Regarding the underlying issue with the 2 phase StreamingAgg, I did not
quite understand the comment
> Currently for simple cross join query with aggregate function, physical
rules are applied in order, which is wrong and results into PlanningException:
This is not correct, since rules in Volcano planner are applied iteratively.
So there could be an initial state where a physical rule did not match but
subsequently after other transformations, it could match and be triggered. I
would suggest enabling Calcite tracing to get a better idea of what's going on
with the distribution traits of the NestedLoopJoin that is causing the
downstream StreamingAgg to not get planned with multi-phase aggregation.

I noticed that this issue with aggregate and low slice target doesn't relate
only to cross-join queries. As a workaround we can bypass unsuccessful 2-phase
aggregation by disabling _planner.enable_multiphase_agg_ option.
@amansinha100 , @vvysotskyi can we proceed with merge of this PR ? So then
this issue with slice target will be fixed as part of
[DRILL-6839](https://issues.apache.org/jira/browse/DRILL-6839) .

Hi @amansinha100 . Thanks for your active involvement, I investigated the
issue and found that:
when option `planner.slice_target` is set to low value, then StreamAggPrule
at the first match will try to create 2 phase plan, but method
call.transformTo(newRel) won't be called (means that rule results are ignored),
because the rule matches at the very early stage of physical planning, there
aren't rels matched by new traitSet with physical convention. Currently for
simple cross join query with aggregate function, physical rules are applied in
order, which is wrong and results into PlanningException:
Prel.ScreenPrule
Prel.ScreenPrule
Prel.ScanPrule
Prel.ScanPrule
ProjectPrule
ProjectPrule
Prel.NestedLoopJoinPrule
ExpandConversionRule
ExpandConversionRule
The problem may be fixed either by returning false from
StreamAggPrule.create2PhasePlan(call, aggregate) for cross join queries, so
then StreamAggPrule will be applied successfully at early stage. Or another
option is to change NestedLoopJoinPrule left and join node's distribution trait
from ANY to SINGLETON, which then results in activation of ProjectPrule ->
StreamAggPrule etc. So then StreamAggPrule is activated again, but now at the
right stage when it can be applied successfully.
@vvysotskyi suggests to proceed with second option, but in order to do this
I need to investigate more about how changing of the distribution traits for
NestedLoopJoinPrule left and join node impacts physical planning. And then, if
possible, try to activate necessary rules without distribution trait change.
@amansinha100 I'd appreciate if you could share your thoughts about the
options.

Review comment:
Hi @ihuzenko , have you tested on Sqlline ? (not just through unit tests).
On my MacBook this is how it displays (all one line):
Error: UNSUPPORTED_OPERATION ERROR: This query cannot be planned possibly
due to either a cartesian join or an inequality join. If a cartesian or
inequality join is used intentionally, set the option
'planner.enable_nljoin_for_scalar_only' to false and try again.
BTW, can you check the other comment I had provided..we would need to fix
that issue.

The formatting of the message is still incorrect. Also, I ran some test
queries and found an issue. After I set the `enable_nljoin_for_scalar_only`
flag to false and set the `slice_target` to a small number (to simulate joining
slightly bigger tables), the cross join planning still fails. This could be a
pre-existing issue but since now we are explicitly supporting cross join, can
you check why the query fails.

Review comment:
Yes, at this moment we can detect that it's explicit cross join because here
inspected object is SqlNode, but later after conversion to RelNode this
`JoinType.CROSS` will be lost, instead we only have `JoinRelType.INNER` in the
node. So to preserve original type additional tricks with query context are
necessary.
What you suggest is actually **Option 2** from my comment in
[DRILL-786](https://issues.apache.org/jira/browse/DRILL-786) , but as I
remember we agreed to go with **Option 3** . So what are the reasons to move
back and use Option 2 ?

Review comment:
Just to for the clarification is that for implicit cross joins and explicit
cross joins do we have joinType set to CROSS by the calcite. If not then can we
not distinguish them and only enable the explicit CROSS joins all the time??

Igor Guzenko commented on DRILL-786:
Looks like we agreed to move on with option 3 without changing default value of
planner.enable_nljoin_for_scalar_only. Also I'll update error message *from*
"This query cannot be planned possibly due to either a cartesian join or an
inequality join. "
*to*
"This query cannot be planned possibly due to either a cartesian join or an
inequality join.
If cartesian or inequality join is used intentionally, set option
'planner.enable_nljoin_for_scalar_only' to false and try again."

Yes, option 3 makes the most sense. The default value (TRUE) of the option
serves as a defensive check. When the user sets it to FALSE they know what they
are getting into rather than Drill surprising them.

Hanumath Rao Maduri commented on DRILL-786:

IMO, the option 3 is what the short term solution for this problem was. i.e
Treat the explicit CROSS JOIN and implicit cross join same. Planner should
generate the plan when the flag is enabled (which is true by default) for
scalar query cases. Otherwise it should throw an error.
I am fine with the option 3 but I am not sure if changing the default value is
needed.

Since option 1 cannot be implemented, I'm fine with option 3 and changing the
default option value. Also, I would recommend adding more tests with the cross
join in different cases and for {{CROSS APPLY}}.

Igor Guzenko commented on DRILL-786:
We considered 3 possible options how the feature could be implemented. Note, in
text below when I mention option is enabled or disabled it relates to
*planner.enable_nljoin_for_scalar_only* option.
*Option 1. (Perfect case) :*
Allow nested loop only for nodes that originated from explicit cross join
syntax but prohibit implicit cross joins when option is enabled. So such query
should fail when option is true:
{code:java}
SELECT *
FROM cp.`tpch/nation.parquet` a, cp.`tpch/nation.parquet` b CROSS JOIN
cp.`tpch/nation.parquet` c
{code}
Because cross join of *a* and result of (*b* x *c*) is implicit and should
depend on option value. But based on my investigation, {color:#d04437}it's
really hard to implement this approach, it requires a lot of time and includes
a lot of changes to Apache Calcite.{color}
*Option 2. (Allow all queries with explicit cross join syntax)*
We can allow nested loop join for all queries that contain explicit cross join
syntax regardless of option value. For example following queries will work in
such case:
{code:java}
SELECT *
FROM cp.`tpch/nation.parquet` l CROSS JOIN cp.`tpch/nation.parquet` r
{code}
{code:java}
SELECT *
FROM cp.`tpch/nation.parquet` a, cp.`tpch/nation.parquet` b CROSS JOIN
cp.`tpch/nation.parquet` c
{code}
But queries that don't contain explicit syntax, will still be dependent on the
option. For example the following query won't work when option is enabled:
{code:java}
SELECT *
FROM cp.`tpch/nation.parquet` a, cp.`tpch/nation.parquet` b
{code}
*Option 3. (Allow cross join syntax only when option enabled)*
This approach is just more narrow case of the previous one. We could allow
explicit cross join for enabled option, and prohibit it for disabled option.

Igor Guzenko commented on DRILL-786:
I've tried addition of joinContext map to Calcite's Join class and passed it
through each point where join instance may be copied or recreated:
JoinToMultiJoinRule.java
LogicalJoin.java
LoptOptimizeJoinRule.java
MultiJoin.java
MutableRels.java
PigRelFactories.java
RelBuilder.java
RelFactories.java
RelStructuredTypeFlattener.java
SqlToRelConverter.java
SubQueryRemoveRule.java
But even with such verbose changes I wasn't able to overcome problem when both
implicit and explicit cross joins are present in one query and option
{color:#59afe1}planner.enable_nljoin_for_scalar_only {color:#33}is set to
true{color}{color}. Such query should fail with exception that says: "This
query cannot be planned possibly due to either a cartesian join or an
inequality join", {color:#d04437}but it works{color}... I suggest to leave
this case and simply enable NestedLoopJoin when explicit cross join is present
in original query. Such solution may be implemented more easily and it won't
require any changes to Calcite.

Ihor Huzenko commented on DRILL-786:
As you may know CROSS JOIN syntax works fine when option
{color:#59afe1}planner.enable_nljoin_for_scalar_only{color} is set to false.
But main goal of this task is to allow explicit cross joins in queries when
option is enabled and at the same time disallow other ways to execute cross
joins (for example, list tables via comma in FROM section of query without
condition) while option is enabled.
The main idea about how we could implement this task is to allow usage of
NestedLoopJoin in two places where mentioned above option is checked:
#
[DrillJoinRelBase.java|https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/planner/common/DrillJoinRelBase.java]
method *computeSelfCost*, line: _if
(PrelUtil.getPlannerSettings(planner).isNlJoinForScalarOnly())_
# [NestedLoopJoinPrule.java
|https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/planner/physical/NestedLoopJoinPrule.java]
method *checkPreconditions* line: _if (settings.isNlJoinForScalarOnly())._
But we should allow it only if our current join rel node is actually originated
from explicit cross join in SQL query. Here is where the main challenge comes
in, at this points we don't know that the rel node is explicit cross join.
Because after invocation of Calcite's
org.apache.calcite.sql2rel.SqlToRelConverter, converted SqlNode becomes
LogicalJoin rel node with type INNER, see SqlToRelConverter:
{code:java}
private static JoinRelType convertJoinType(JoinType joinType) {
switch (joinType) {
case COMMA:
case INNER:
case CROSS:
return JoinRelType.INNER;
case FULL:
return JoinRelType.FULL;
case LEFT:
return JoinRelType.LEFT;
case RIGHT:
return JoinRelType.RIGHT;
default:
throw Util.unexpected(joinType);
}
}
{code}
I tried to add custom RelTrait and with help of reflections magic I was even
able to overcome HepPlanner's conversions of LogicalJoin nodes. But then I got
an error from VolcanoPlanner's code:
{code:java}
if (traits.size() != traitDefs.size()) {
throw new AssertionError("Relational expression " + rel
+ " does not have the correct number of traits: " + traits.size()
+ " != " + traitDefs.size());
}
{code}
So it's impossible to use traitSet for marking that rel node is came from
explicit CROSS JOIN syntax. I see two options how we could overcome this
problem and both of them include changes to Calcite's LogicalJoin class (just
because it's final class :():
1) Either add additional flag and preserve it between recreation of LogicalJoin
instances, as it was done for field:
{code:java}
private final boolean semiJoinDone;
{code}
But major disadvantage of this approach is that updated constructors will break
other clients code.
2) Add ability to register static callback function that will be called after
creation of new instance inside copy method, and accept both oldRelNode and
newRelNode. So then we could trace ids of LogicalJoin instances since creation
of first such instance in org.apache.calcite.sql2rel.SqlToRelConverter.
This are all ideas that I have now. I'm very new to Drill and Calcite and maybe
I don't see other good alternatives. Dear drillers, could you please take a
look and share your thoughts about possible options ?

Any movement on this?
Multiple tools (Tableau, MicroStrategy as examples) generate cross joins with
dimension tables when building dashboards/analytics.
