Azure Databricks storage or data lake
I'm creating a structured streaming job that stores its data in a databricks delta database. I'm confronted with the option of storing the checkpoint location and data from the delta database in either ...
1. a normal dbfs location like "/delta/mycheckpointlocation" and "delta/mydatabase"
2. a mounted directory from a data lake like "/mnt/mydatalake/delta/mycheckpointlocation" and "/mnt/mydatalake/delta/mydatabase"
If I understand correctly the data in nr1 will be persisted in a blob storage while the data in nr2 would be stored in the data lake (assuming it's mounted on /mnt/mydatalake)
What considerations are there to decide to store stuff like the checkpoint location and the delta database in either 1 or 2?
