@uranusjr How are we getting along on this one? Can we get this in rc1?

[uranusjr]

I have been working on other more higher priority issues. There’s still one more. Hopefully I can get to this next week, but can’t promise.

Can you see if we can get it in before rc2 (this week - Thurs) if possible? And verify it by using XComObjectStorageBackend

[core]
xcom_backend = airflow.providers.common.io.xcom.backend.XComObjectStorageBackend

[common.io]
xcom_objectstorage_path = s3://conn_id@mybucket/key
xcom_objectstorage_threshold = 1048576
xcom_objectstorage_compression = gzip
