"Scheduled actions do not run at the exact time they were expected"
|
|
-------------------------------------------------------------------
|
|
|
|
On the Odoo.sh platform, we cannot guarantee an exact running time for scheduled actions.
|
|
|
|
This is due to the fact that there might be multiple customers on the same server, and we must guarantee a fair share of the server for every customer. Scheduled actions are therefore implemented slightly differently than on a regular Odoo server, and are run on a *best effort* policy.
|
|
|
|
.. warning::
|
|
Do not expect any scheduled action to be run more often than every 5 min.
|
|
|
|
Are there "best practices" regarding scheduled actions?
|
|
-------------------------------------------------------
|
|
|
|
**Odoo.sh always limits the execution time of scheduled actions (*aka* crons).**
|
|
Therefore, you must keep this fact in mind when developing your own crons.
|
|
|
|
We advise that:
|
|
|
|
- Your scheduled actions should work on small batches of records.
|
|
- Your scheduled actions should commit their work after processing each batch;
|
|
this way, if they get interrupted by the time-limit, there is no need to start over.
|
|
- Your scheduled actions should be
|
|
`idempotent <https://stackoverflow.com/a/1077421/3332416>`_: they must not
|
|
cause side-effects if they are started more often than expected.
