In rare-ish cases, a visualization may need to execute multiple
|
|
queries. That is the case for FilterBox or for time comparison
|
|
in Line chart for instance.
|
|
|
|
In those cases, we need to make sure these queries run before the
|
|
main `get_payload` method gets called, so that the overall caching
|
|
metadata can be right. The way it works here is that if any of
|
|
the previous `get_df_payload` calls hit the cache, the main
|
|
payload's metadata will reflect that.
|
|
|
|
The multi-query support may need more work to become a first class
|
|
use case in the framework, and for the UI to reflect the subtleties
|
|
(show that only some of the queries were served from cache for
|
|
instance). In the meantime, since multi-query is rare, we treat
|
|
it with a bit of a hack. Note that the hack became necessary
|
|
when moving from caching the visualization's data itself, to caching
|
|
the underlying query(ies).
