is there a link to documentation? all new language features should be documented. I also don't see documentation for CREATE MATERIALIZED VIEW

[mayankgarg1990]

That is a good point. I checked the PR and there is no documentation in the PR :( https://github.com/prestodb/presto/pull/15996/files

What would you recommend in this situation ?

Also @highker - your thoughts?

[rschlussel]

Is the feature complete? I'm not sure the feature is that usable without documentation. Maybe leave out the release note and @gggrace14 or @highker can add documentation for CREATE MATERIALIZED VIEW and REFRESH MATERIALIZED VIEW and we can add a release note then.

[gggrace14]

Yes, the feature is complete with CREATE, REFRESH & SELECT from MATERIALIZED VIEW. We would love to add documentation and release note.

We are allowed to add release note afterwards in the repo, is it correct? I will sync up w/ @highker offline on how to add documentation and release note. Sorry, first time to do it.

[mayankgarg1990]

I will remove the release note from this release. @gggrace14 feel free to introduce another release note with link to the doucmentation in the release note
