Has anyone worked with a large volume of events? For example, the task is to split events into pages of 50 and retrieve them by page number. But for this kind of pagination via queries, you still have to use the event history function, which essentially needs to first retrieve all the events and then iterate through them with a query. Or am I missing something?

Should the filter function return a new table or not?

I've encountered a problem where after applying dr(0) to the filter function's result, it returns the first row of the original table, not the first row after the function.

I think it's a bug.

The LIMIT parameter isn't working in the function query. A query like this:

SELECT *
FROM utilities:variableHistory("users.username.models.modelname", "dataTableVariable")
LIMIT ?

results in the error:

Query syntax is not valid: Encountered " "?" "? "" at line 3, column 7. Was expecting one of: <S_NUMBER> ... <S_NUMBER> ...

Is there a way around this?

Has anyone used the Web UI Event Log component? I can't figure out how to highlight the rows in the color I want. I specified a color in the event filter (the highlight color), but the log highlighting was not applied in the web client. I tried using the element style/row color, but that didn't work either.

Is it even possible to color the log?
