jarulraj · 2023-01-02T23:40:41Z

Based on Add support for COUNT, SUM, AVG, MIN, MAX #519
Brings back pip package testing in CI
Reduces verbosity of YOLO model
Update links in readme to point to the stable version in read-the-docs
Add support for toxicity detection based on feat: Add toxic meme detection via UDF #516
Add support for querying based on video timestamps (based on feat: Support timestamps and querying for timestamps #520)

I don't understand this logic. Are we hardcoding * to id in the parser? If yes, I guess even though it is hacky, it saves us from handling this corner case in the binder. We could change it to IDENTIFIER_COLUMN, which is supposed to be a unique row id in all the tables.

Yes. This query currently works. I was also worried if "id" will be always present. How should I change it to IDENTIFIER_COLUMN?

The unit tests do not create tables using IDENTIFIER_COLUMN -- so the test case fails.

Yeah, I verified we don't support projecting IDENTIFIER_COLUMN, which causes the binder to fail.
id won't work for images or other tables. Ideally, the binder should take care of it.
An if condition here should fix it.

Is it aggregating each row of the array? If yes, I suspect that will break the execution logic.

Yes, how will it break the execution logic?

The NDARRAY case is for object detection array etc. The normal case is the one that existed earlier -- self._frames = self._frames.agg([method])

I have reverted back the NDARRAY case as it does not make sense.

Aggregate on ndarray and primitive column will result in different row counts.

We have a different set of aggregate operators to apply row-wise aggregates likeArray_Count

We should add a test case with aggregate on ndarray column.

When the query operates on an ndarray column, it does not reduce it to a single row. It actually keeps as many rows around as the number of the rows in the input column.

I have reverted back the NDARRAY case as it does not make sense.

Do we raise an error if the query tries to aggregate on an array column? We should add a test case to verify it. Thanks!

I changed it to use list for the append operation. DataFrame throws a lot of warnings. You can refer to other udfs.

Did you push your change?

Isn't it no-op?

This is a timestamp UDF.

SELECT id, seconds, Timestamp(seconds) FROM MyVideo WHERE Timestamp(seconds) <= "00:00:01";
