omit the histogram loading state, allowing runQuery to abort and restart an
active histogram request. Update each guard around runQuery, including the
RefreshIntervalDropdown handler, to also require !isLoadingHistogramData before
refreshing.

It seems we are mixing type assertion with the response status. We could use a more idiomatic way and turn this the type check into a typeguard and check the response status inside the caller (getFetchConfig)

I was not exactly sure what you meant, especially with regards to the getFetchConfig but I understand what you mean about the mixing type assertions with data assertions. I've split this up into a chain of validations, with the type assertions being separate from the data assertions

Sorry I meant this https://www.typescriptlang.org/docs/handbook/2/narrowing.html#using-type-predicates to narrow down the type of the response data after verifying the response is successful
There was a problem hiding this comment.
Ah gotcha, yeah that is pretty similar to what I had done, but the type predicates only need 1 function call while the assert needs 2. I'll fix it on tuesday, but thanks for the response so late. Now go and enjoy your time off

By removing the abort logic, rapid clicking could generate multiple request. It seems now we are only filtering the responses but the request are still running and consuming frontend and backend resources.

I've expanded the throttle logic you had added in the getLogs to the getMoreLogs as well. I've also added a longer throttle when the query is identical, preventing the user from spamming the sync or run query button

should we add this guard inside runQuery so we don't have to duplicate them in all pages?
There was a problem hiding this comment.
We can't move this up into runQuery or getLogs since the user needs to be able to make requests that have different parameters even while a query is currently pending. I have updated this to be a bit more clear on the ownership, adding an enableRefresh parameter to the RefreshIntervalDropdown which actually prevents the running inside the component which I think is where it should belong

In `@web/src/hooks/useLogs.ts`:
- Around line 443-447: Update the duplicate-request check in the
runQuery/getLogs flow to require an exact namespace match and the regular
request mode: use currentNamespace.current === namespace and ensure
currentLastTimestampNs.current is undefined before treating requests as
identical. Preserve the existing sameQuery, sameTimeRange, sameDirection,
sameTenant, and sameSchema checks.
In `@web/src/pages/logs-page.tsx`:
- Line 214: Update the refreshEnabled prop passed to RefreshIntervalDropdown to
use the inverse of isLoadingLogs, so refreshes are enabled after loading
completes and disabled while logs are loading.
