Switch Climate Analysis to Multioperation #3221

merged 3 commits into from Dec 31, 2019

rajadain commented Dec 31, 2019


To reduce Celery overhead and the possibility of unchecked chord_unlock calls, we switch Climate analysis to the multioperation geoprocessing call. This results in a more efficient, faster analysis that is easier to cache.

Connects #2782



Testing Instructions

  • Check out this branch and debug celery $ ./scripts/
  • Select a WKAOI (preferably a fresh one that would not have been cached on your local machine) and analyze it
    • Ensure all analyses complete successfully, including Climate
  • Select the same WKAOI on staging
    • Ensure the Climate analysis has the same numbers as your local
  • Also try with drawing a shape, so it doesn't use the cache
    • Ensure it completes successfully
This makes explicit the input and output expected of
the `collect_climate` method.

To reduce Celery overhead and the possibility of unchecked
`chord_unlock` calls, we switch Climate analysis to the
multioperation geoprocessing call.

`analyze_climate` and `collect_climate` tasks are merged
into one, to expect the new input. Their collective output
remains the same as before.

The view is considerably simplified. Geoprocessing config
is updated to remove the solo calls to `ppt` and `tmean`,
and to have a single `climate` call that gathers data from
all 24 rasters.

Looks good. It's hard to compare performance with local vs staging, but it does seem to be an improvement.
