### SUMMARY This will be one of the many PRs to address perf issues raised in #15518 . Currently the Dashboard page will wait for both `datasets` and `charts` data to start rendering, however the datasets data are only used in filter indicators and filter boxes and should not block us from rendering other charts. In our case, the `datasets` endpoint is often much slower because we have a giant single-source-of-truth datasource with thousands of metrics and columns. Unblocking rendering from the datasets endpoint should speed up the page rendering a little bit. In our use case, it's often a matter of a full second. It's not easy to simply remove `datasources` from Dashboard state as that would involve letting the filter indicators and filter box fetching datasource metadata themselves. ### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF N/A ### TESTING INSTRUCTIONS Go to dashboard page, make sure everything still renders correctly. ### ADDITIONAL INFORMATION <!--- Check any relevant boxes with "x" --> <!--- HINT: Include "Fixes #nnn" if you are fixing an existing issue --> - [ ] Has associated issue: - [ ] Changes UI - [ ] Includes DB Migration (follow approval process in [SIP-59](https://github.com/apache/superset/issues/13351)) - [ ] Migration is atomic, supports rollback & is backwards-compatible - [ ] Confirm DB migration upgrade and downgrade tested - [ ] Runtime estimates and downtime expectations provided - [ ] Introduces new feature or API - [ ] Removes existing feature or API -- This is an automated message from the Apache Git Service.
