@BaDos , did you have a chance to look into it?

Could you please consider adding support for the new use_application_lock setting (see https://devdocs.magento.com/guides/v2.4/extension-dev-guide/indexing.html#using-application-lock-mode-for-reindex-processes)? This would help to mitigate this problem.

@andriyShevtsov Why has this issue been closed? Neither is the original problem solved nor has the new option use_application_lock been implemented. By closing this issue you just ignore the fact that indexation stays in a bad state after deployment and ece-tools doesn’t try to help with it.
