Thanks for creating this PR. Could you add the document?

It seems write query fails if we omit the default database from connection-url. It's different behavior comparing to other JDBC based connector, so it would be better to mention it.

@pgagnon is this a read-only connector or can it insert/update data back into snowflake? does it support xml/json snowflake functions (https://docs.snowflake.com/en/sql-reference/functions-semistructured.html) ?

@tooptoop4 The answer to the second question is no.

Sorry I have been out of pocket for a while. I have received a couple of inquiries about it over the last week, so I will rebase it and address reviewer comments over the weekend.

Thanks for raising this PR. Looks good to me. Can you squash all the commits.

@findepi your insights ?

Please make sure there is an issue to cover SF testing.

Do you have any idea how to provide test coverage for that? Now it sounds very easy to have a regression unnoticed here. What are your thoughts?

@Praveen2112

I think Snowflake doesn't have a free account or a test account. Trial period is for 30 days. We can verify it manually but it is a tedious process (like we do for Redshift connector)

We can verify it manually

We could, but currently there are no tests that we could execute against manually created testing environment.

@Praveen2112

We can add Integration and DistributedQueriesTest test but we have to skip those tests in the GHA.

@pgagnon would you be able to add aggregate pushdown like 193872a#diff-e4b92558819e35928d8d20100000291dda1e15cf907c1d2f06ba4015b0afd6cc ?

We're sort of blocked on a proper testing strategy right now, but I'll make sure to rebase soon so that you can at least play with the branch.

Hi @pgagnon. Not to be pushy but any update on the rebase?

Hi @pgagnon! First of all, thanks for being working in this connector. We are really looking forward to use it!
I'm a data eng at centro.net and we have data in our SF databases and want to combine it with other data marts (HIVE and Mysql so far).

I've read this thread and, if I understood correctly, the PR is blocked due to some tests that can't be run as SF does not provide something like a docker image to code decent ITs. We run into this problem last year when we're developing a service and realized there wasn't a way to mock SF. We work it out by hitting the real SF from our Jenkins nodes (pointing to a dev DB). Not an ideal solution, but is working. However, it's true this tests won't be possible without a SF account.

I wonder if I could help in any way, maybe by running those manual tests mentioned by @Praveen2112 or helping you coding something as well, I'd be glad to help.

@pgagnon Thanks for working on this feature.

@Praveen2112 @findepi Thanks a lot for the reviews on the initial PR. Could we see how to break the stalemate around testing ? While working on hadoop/hdfs project, we faced sometimes similar'ish challenges, and the way we sometimes adopted was to reflect the state properly in the documentation by using words such "Feature is in experimental phase". What are your thoughts about it ? With a plethora of downstream datasources, we may at times run into these sort of issues specific to certain connectors and hence a good way would be to reflect the state in the respective connector doc page. Happy to chime in and help in whatever way to get this across the finish line.
