feat: Add parquet upload #14449

exemplary-citizen · 2021-05-03T18:05:05Z

SUMMARY

Allow CSV upload form to accept parquet file. Went in this direction so as not to exacerbate what was brought up in #13834 by adding a new form specifically for parquet files. I believe small modifications can be made to this PR to accommodate feather and orc files.

@john-bodley @villebro just wanted to follow up on this in case it got lost in the shuffle. How should we proceed on this PR?

This appears to change the behavior of the existing CSV upload functionality by specifying columns. Can you add some tests around this?

added a scenario to test_import_csv that tests uploading a CSV with specific columns

A few comments:

While it's convenient to add this functionality to the CSV upload form, I feel this should be in a form of its own, as the majority of the current fields are specific to CSV only (IIUC only usecols is needed for Parquet upload)
If the CSV upload form will also handle Parquet, the title needs to be updated to reflect this. However, I'd personally prefer moving this into a form of its own.
it would be nice if the form could handle directories/zip files, as it's fairly common to have partitioned data that is split up into multiple Parquet files. As pandas also supports uploading from a directory path, this would be a great feature to avoid having to manually append upload each file.

superset/views/database/forms.py

-                config["ALLOWED_EXTENSIONS"].intersection(config["CSV_EXTENSIONS"]),
+                config["ALLOWED_EXTENSIONS"].intersection(
+                    config["CSV_EXTENSIONS"].union(config["OTHER_EXTENSIONS"])
+                ),


You need to add the union to the error message below.

exemplary-citizen · 2021-05-25T07:31:51Z

Yeah I agree that this probably belongs in a separate form. Just went in this direction because creating a new form would mean that we'd effectively be abandoning #13834. I'll go ahead and get started working on a new form for parquet/directory/zip unless @junlincc @srinify @Steejay have any ideas on how to better consolidate these forms. I believe wtforms has a MultipleFileField class that should allow us to upload entire directories. We can also introduce this change to the CsvToDatabaseForm so users can upload multiple CSVs at a time.

@exemplary-citizen there's a linting error in one of the files. You can either setup pre-commit hooks or apply the diff below to fix the problem:

@exemplary-citizen sorry to bother you again, but we've recently updated the version of pylint which appears to be causing some new linting issues. Do you want to fix this or is it ok if I jump in and resolve the remaining ones?

LGTM! While testing I found some edge cases that caused trouble, but those can be improved upon later (I'll try to open up a PR for some of them; will tag you for a review when I do).

Hi @villebro and @exemplary-citizen , I am using Superset v2.1.0 docker compose and I couldn't upload a parquet file to Superset. Is this request get deprecated in new version?

Hi @villebro and @exemplary-citizen , I am using Superset v2.1.0 docker compose and I couldn't upload a parquet file to Superset. Is this request get deprecated in new version?

I am sorry for the question above, I see the Upload columnar file to database now.
I am trying to programatic upload file from S3 to Superset db because the performance of slice query to Athena via pyAthena are so slow compare to postgresql query directly to superset db.
As I can see Athena doesn't receive 25 requests at the same time (my dashboard has 25 charts in 1 page) but doing it one by one and send the result back to Superset. I have tried domain sharding, increase gunicorn workers + threads but my Superset on docker compose didn't improve performance.

Is there a way to programatically import parquet files to superset db? Thanks
