Discuss what is the best way control program flow for the forecast fetch + trigger evaluation

lucernae commented 4 years ago

Summary of current implementation is written here: https://github.com/inasafe/inasafe-fba/tree/master/documents/backend-development

Trigger evaluation is blocked because forecast fetch waits for materialized view refresh. So, if we implement forecast fetch as db triggers, it will not work since it will wait for the current trigger sessions to finish. Forecast script needs to commit the changes, then evaluate the trigger.
