Hello,
I would like to start introducing the failure activity into the synapse pipelines.
For example, when an activity fails then it goes into the failure activity...
Question:
As our current destination(Sink) are .parquet files into blob storage, how should I structure the failures?
For example, if I create a folder called "Errors" in the blob storage, then should the errors be created in .parquet as same as other files?
Thank you

Hello @arkiboys and welcome back to Microsoft Q&A.
I am confused by your ask. Are you talking about the fault tolerance, which records rows that failed to insert? Or are you talking about the activities using on-failure dependencies? These are 2 separate things.
Fault tolerance and logging settings of copy activity:
On-failure dependency:

When an activity fails, it goes in to whatever you configured it to do... if you haven't configured anything, it will "bubble up" until something has handled it
If you're meaning invalid rows being rejected, they go to a text file (at least by default, not sure if that's configurable)
Yes, on failure dependency.
In your example, instead of copy data1, I would like t o have an activity to populate .parquet file.
What activity do I use?
Thank you
You use a copy activity with an empty delimited text file as source, and parquet as sink. Use the additional columns feature to pass the error message into a new column.

Thank you for the details
