Calculate dynamically if granularity is not set #150
Description
When sending a query, it would be nice to have a function that dynamically calculates the granularity when the granularity is not set.
In the (old) plugin I am currently using, if 'custom granularity' is not set, it is converted as follows:
| interval | granularity |
|---|---|
| 24 hour | 15 minutes |
| 1 month | 1 hour |
| 1 year | 1 month |
etc.
I guess with this part (https://github.com/grafana-druid-plugin/druidplugin/blob/33af5d544755a7bbcf7d72fcbd9673ef66a2840c/src/datasource.ts#L67)
However, when I tested the new version, I found that the feature is not there.
Currently, when I set Granularity to 'Simple:minute', 1 hour, 1 week, 1 month, and 1 year intervals all use granularity as minute.
If the number of panels is large and the time interval is long, refreshing can take a long time and consume a lot of memory due to the large amount of data being returned.
The version I am currently using is:
Grafana: v5.4.5
druid plugin : v0.0.5
The version I'm using for testing is:
Grafana: v9.3.6
druid plugin: v1.4.1
thank you !
