Group by aggregation for table joins

Use case: Being able to aggregate data across multiple tables and grouping by certain fields.

Feature description: Let’s say I have two tables: tableA, tableB. tableA contains all of my metadata and tableB contains important timing information relevant to a record in tableA.

For example: tableA contains the following columns:

id STRING,
browser STRING,
browserversion STRING,
os STRING

tableB contains the following columns:

testid STRING,
testname STRING,
startdate LONG,
enddate LONG,
time STRING

Example query:

SELECT avg(tableb.time), tableb.testname FROM tableb INNER JOIN tablea on tableb.testid = tablea.id GROUP BY tableb.testname;

Error that I currently get:

ValidationException[GROUP BY on JOINS is not supported]

We’ve merged support for GROUP BY on joins via https://github.com/crate/crate/pull/5339 - it’ll be part of the next feature release (1.2)
