Add option to disable live queries

[wmeler]

Sometimes druid response is slow and it would be better to disable live queries that refresh result view while building the final filters/split/measure/view set to prevent overloading druid with unneccessary queries.

I propose to:

• change auto update "Off" mode behavoiur to not refresh result view
• add auto update "Live query" mode that would reflect current "Off" mode
• pull "Update now" button from auto update menu and place it over the display menu

I'd appreciate feedback and discussion.

• add auto update "Live query" mode that would reflect current "Off" mode

Don't want to expose myself, but - how "Off" works right now? I thought it disables auto refresh completely?

Oh, I get it now! That's a big change from UX perspective. But I like how you made it backwards compatible.

Probably, in new mode we would grey out visualisation/pinboard after changes and enable "update now" (or just play icon) button.

That also affects url - should we change url when someone changes filters/splits but doesn't update visualisation? That sounds like a lot of ifs in weird places ...

The fact is that only few users notice update now button in refresh menu and click F5 or CTRL-R which cost more load on servers.

My colleagues say that pinboard and filters should keep refresh on every filter change because it is crucial in qube query construction. We could gray out results instead.

I think that url should change and reflect filter/split/measure/display state - if you refresh page it should load results.

I'm getting more and more convinced. Few notes.

1. I think this setting is separate from Auto update menu. This is something different.
2. We need config option for default mode. So admin can pick one for users.

• Do you think we should keep user mode in local storage? Do you expect users to change this setting for themselves? Would they expect this change to persist? I'd like to avoid local storage if we really don't have to add it.

3. Only Visualisation panel can become stale. Filter menus and pinboard refreshes just like today.
4. Because it affects only visualisation panel, we can put UI there. After changes it become stale so we grey it out and show overlay with information an "Run" button.

I won't argue, but it's related so it could be in this place.

Personally I would not store live query mode in local storage - I'd like to have different behaviour on different browser tabs. I'd like to force users to disable live queries on very big, heavy datacubes - so I'd prefer to have this setting in configuration on datacube level.

3. Only Visualisation panel can become stale. Filter menus and pinboard refreshes just like today.
4. Because it affects only visualisation panel, we can put UI there. After changes it become stale so we grey it out and show overlay with information an "Run" button.

That is great idea, but I still recommend pulling "update now" button from auto update menu.

Oh, I didn't think about it. Makes sense. Probably every admin of turnilo already rolled out some config generator script so repetition there wouldn't be a problem but granularity is definitely a win.

Yeah, button for "Evaluating" changed filters will be in the middle.

"Update now" button require some rethinking. We'd like that users will embrace browser - if you need to refresh stale tab, just use browser refresh button. That will refresh everything, not only data but data cube max time which can impact time filter calendar view and who knows what else.

Out of curiosity, do you use auto refresh on any of your cubes?

Time filter should update itself on every form display (#527)

It's very rare. I can't remember if I used it last year.
