Number based columns representing time in custom format cannot be used as timestamp column in Druid. (#9877)
* Number based columns representing time in custom format cannot be used as timestamp column in Druid.

Prior to this fix, if an integer column in parquet is storing dateint in format yyyyMMdd, it cannot be used as timestamp column in Druid as the timestamp parser interprets it as a number storing UTC time instead of treating it as a number representing time in yyyyMMdd format. Data formats like TSV or CSV don't suffer from this problem as the timestamp is passed in an as string which the timestamp parser is able to parse correctly.

SQL: More straightforward handling of join planning. (#9648)
* SQL: More straightforward handling of join planning.

Two changes that simplify how joins are planned:

1) Stop using JoinProjectTransposeRule as a way of guiding subquery
removal. Instead, add logic to DruidJoinRule that identifies removable
subqueries and removes them at the point of creating a DruidJoinQueryRel.
This approach reduces the size of the planning space and allows the
planner to complete quickly.

2) Remove rules that reorder joins. Not because of an impact on the
planning time (it seems minimal), but because the decisions that the
planner was making in the new tests were sometimes worse than the
user-provided order. I think we'll need to go with the user-provided
order for now, and revisit reordering when we can add more smarts to
the cost estimator.

A third change updates numeric ExprEval classes to store their
value as a boxed type that corresponds to what it is supposed to be.
This is useful because it affects the behavior of "asString", and
is included in this patch because it is needed for the new test
"testInnerJoinTwoLookupsToTableUsingNumericColumnInReverse". This
test relies on CAST('6', 'DOUBLE') stringifying to "6.0" like an
actual double would.

Fixes #9646.

Suneet Saldanha 0ccfe5ca89 Expose JoinableFactory through Guice Bindings (#9271)
* Make JoinableFactory an extension point

This change makes it so that extensions can register a JoinableFactory that
should be used for a DataSource.

Extensions can provide the factories via DruidBinders#joinableFactoryBinder
Known DataSources - like InlineDataSource are provided in the
JoinableFactoryModule. This module installs a FactoryWarehouse that is
used to decide which factory should be used to generate the Joinable for
the provided DataSource.

The ExtensionPoint is marked as Beta since it is not yet clear if this
needs to remain available to other extensions or if the best way to
register a factory is by using the datasource class.

* Add module test

* remove useless bindings in test

* remove ExtensionPoint annotation

* Speed up String first/last aggregators when folding isn't needed.

Examines the value column, and disables fold checking via a needsFoldCheck
flag if that column can't possibly contain SerializableLongStringPairs. This

unnecessary; say, because the time selector didn't yield an earlier or later
value.
