TSVB needs a "tsvb:max_buckets" target setting for auto instead of a default 120 buckets

[Paul-de-Barbeyrac]

Describe the feature:
When interval is set to auto in the Time Series Visual Builder, the TSVB seems to be splitting the selected time range into 120 buckets maximum.

Describe a specific use case for the feature:
This is a serious limitation for the user who wants to see trends over long period of time with a decent granularity. Since he can choose from a few seconds time range to up to years, the alternative to increase the general max_bucket setting and set each time the interval manually based on the time span is not acceptable.

In a nutshell, the wanted feature is a TSVB auto field targetting a tsvb:max_buckets in advanced settings. This setting exists for timelion but not for tsvb.

Thank you

The size here can be increased only if the total number of buckets in the response is under 10,000. Splitting your visualization by Terms or adding many Filter Ratios might push it over the limit. I would propose that instead of using an advanced setting, TSVB should be more dynamic and have a slider that lets users increase the granularity.

Thank you @wylieconlon !
The slider would be indeed a great feature, much appreciated.

In our case, we monitor industrial assets streaming data every 10s. As you recommended, I already have filters setup to target a specific equipment on the vizualisation, but due to this demanding sampling time, I am afraid this 10 000 limit is rapidly reached and prevents looking at long term trends with a decent granularity (as an example 1 year trend is displaying data aggregated over roughly 3 days bucket which is unsufficient for our business needs).

This feature would be nice since the repsonse time on the TSVB is amazingly fast and we could definitely afford to wait a bit longer for a better granularity.

Will follow-up on this. Thank you

In general we are looking at ways to support long-running searches in Kibana, such as #48811 and this effort might be related. Showing denser time series data makes sense for lots of our users.

Is there any update on this ? Just upgraded to 7.10 and see no improvements related to it. Thank you
