## The problem
Issue posthog/posthog#15997 (closed, 40 comments): We're moving a lot of currently available apps to a new export system based on Temporal, which exports events in batches. It's proven to be a lot more reliable than our previous streaming system. ## Done - [x] Best effort duplicate removal (#16354) - [x] Revamp exports UI - [x] S3 exports - [x] S3 key templating (#16591) - [x] Add support for file compression (S3/blob storage, #17233, #17269) - [x] Snowflake exports - [x] Postgres exports (#17045, #17178) - [x] Reliability improvements.
## What fixed it
On PostHog batch exports (the Temporal-based export system): it is not possible to cancel an already scheduled export. If you need an export stopped, you have to let the scheduled run complete and disable or delete the export config so no further runs are scheduled. Maintainer-confirmed in the batch exports mega-issue.
