etr2460 opened a new pull request #9019: [SQL Lab] Cache function names query URL: https://github.com/apache/incubator-superset/pull/9019 ### CATEGORY Choose one - [ ] Bug Fix - [x] Enhancement (new features, refinement) - [ ] Refactor - [ ] Add tests - [ ] Build / Development Environment - [ ] Documentation ### SUMMARY As I tested this further, I realized that this was making a query to every presto and hive db whenever you open SQL Lab or open a new SQL Lab tab. This PR caches the result of the `show function` query as we don't expect it to change often. ### TEST PLAN Add a print statement to the function, see it the first time I open SQL Lab, but then when opening subsequent SQL Lab tabs, don't see the print statement again ### ADDITIONAL INFORMATION <!--- Check any relevant boxes with "x" --> <!--- HINT: Include "Fixes #nnn" if you are fixing an existing issue --> - [ ] Has associated issue: - [ ] Changes UI - [ ] Requires DB Migration. - [ ] Confirm DB Migration upgrade and downgrade tested. - [ ] Introduces new feature or API - [ ] Removes existing feature or API ### REVIEWERS to: @john-bodley @villebro @betodealmeida
