While most of the comments are abou code changes that dont affect users and can be fast followed, there are 2 user facing bugs that we need to address:

There are 3 requests fired when both fields are being loaded and the query is running. I can reproduce this the easiest when ive selected an s3 datasource and refreshed the page. See screenshot

The available fields just dint stop spinning when the page refreshed even once the requests are successful. See secind screenshot

Looks like Flint is breaking on main, get this when running any s3 based SQL query:

server    log   [21:53:31.717] [error][plugins][queryEnhancements] Facet fetch: enhancements.sqlQuery: Error: Data Source Error: Internal Server Error
server    log   [21:53:31.717] [error][plugins][queryEnhancements] sqlSearchStrategy: {

    "reason": "There was internal problem at backend",
    "details": "Glue storage engine is not supported.",
    "type": "UnsupportedOperationException"
  },
  "status": 500
}

Debugging the commits led me this 923cce8. this commit might be the root-cause why we're seeing this weird behavior for flint datasources

ps48 · 2024-10-19T00:26:54Z

Current status:

Rebased my PR on main again - no conflicts as of now
Reverted the dataselector 923cce8 changes on local to test my PR it works
I am able to load and reload pages without any issue
I the bug Ashwin raised on 3 queries being emitted out for fields -> Will take this and other non-blocking comments in fast follow once we get this merged in.

Video of local test with the revert dataselector changes:

  name?: string;
  /** Optional session ID for faster responses when utilizing async query sources */
  sessionId?: string;

+  supportsTimeFilter?: boolean;


can this be controlled based on whether timeField is present in the dataset rather than additional flag?

Today even if timeField is present we don't have support for S3 datasources to automatic time filter injection in the query. This is surely where we want to go towards in future though.

Some older conversations around this: #8337 (comment), #8337 (comment)

does async index patterns mean the metadata like field schema is not stored in the index pattern saved object?

Async index patterns means that the fields are lazy loaded; i.e. the temporary index pattern is created with empty fields and when the fields are loaded in the index pattern gets hydrated with the fields.

this [] creates a different object every time when called, and will trigger a re-render. might be better to add a guard

if loading and fields list is empty, what does UI show? should it indicate that it's loading?

If loading and fields list is empty -> The UI shows the sidebar in the loading state.

Don't have time to pull this down to test, but approving assuming bugs Ashwin brought up are resolved (which appear to be the case from comments)

Other comments are not blocking

Handling of this request should ideally be tested. Can we follow up on this?

does this need to be escaped in anyway or can we trust dataset metadata?

My bad. Still had the older commits when i rviewed. When i pulled down the latest changes, it works
