During last days we have turned on strict input/output mapping validation. Each input/output mapping is checked against the table in Storage if
- all columns exist
- the primary key is equal in both cases
- datatype/indexes/distkey/sortkey or filter column names have the same letter case
Although we tried to detect all breaches of this ruleset beforehand and contact project owners some have unfortunately slipped through. We're closely monitoring all errors and fixing/restarting all failed orchestrations.
In case your project is subject to this issue on a larger scale than a single failure, we're able to remove the validation temporarily. Please contact us at email@example.com with any further questions/requests.
We're deeply sorry for any inconvenience.
