Kibana: [TSVB] Performance degradation and lag on hover / tooltip

[alexfrancoeur]

There seems to be a noticeable lag on high cardinality time series visualizations. If you were to group by say 150 terms, it becomes painfully slow when hovering over to see a tooltip. When there is high cardinality across multiple charts on the same dashboard, this degrades the performance of the entire dashboard. It's possible that this is directly related to the shared cursor across TSVB visualizations.

In the below example you'll see the difference between 10 series and ~30. You can already see a noticeable lag.

10 different series

~30 different series

It's worth noting that other competitors do not seem to have this problem.

@alexfrancoeur just an update of current status with the new elastic-charts.
beside the ugly colors and the randomness of the data, here you can see 100 series with 200 data point on each without any lags.
We didn't implement the shared cursor across charts yet, but I think it will not influence a lot the current performance

@markov00 that is amazing 👏 🙇 ❤️

this is a single barchart series with 15000 bars.
It will take 2 seconds to render more or less, but then it's super responsive on hover

[alexfrancoeur]

but can it do 15001 bars? (just kidding, this is amazing)

Given that TSVB now uses Elastic charts, this issue should no longer appear. I'll be closing it, please feel free to leave a comment in case you have the feeling the problem still persists.
