~~@cjao can you see if you make this true in a way for other waits as well like env and deployment ? ~~ Please ignore |
The previous `GET /dispatches/{dispatch_id}` endpoint was trying to do
too much. Its responsibilities are now separated into two endpoints:
* `GET /dispatches`: bulk query dispatch summaries (including status)
with options to filter by `dispatch_id`, sort chronologically, and
also limit the output to status only.
* `GET /dispatches/{dispatch_id}`: download manifest
To achieve the desired behavior of `get_result(id, wait=True)`, the
client
1. Polls the dispatch status by querying the first endpoint.
2. Downloads the manifest after the dispatch has reached a final
status.
The server no longer returns 503 errors when the dispatch is not yet
"ready". A 503 status code is not entirely accurate here because it is
intended to convey temporary service unavailablity resulting from
server overload or rate limiting. However, the fact that the workflow
is still running does not indicate any fault of the server.
These changes will allow `get_result(dispatch_id, wait=True)` to wait
as long as required instead of erroring out after some time.
Supporting improvements:
DAL: Add sorting and pagination to Controller
DAL: improve bulk get when retrieving only some columns
Directly select the specified columns instead of retrieving the whole
ORM entities and deferring column loading using load_only
