Can we assume the path to the managed tables in the hive_metastore is reliable?

Managed tables are stored under the /user/hive/warehouse, which is also mentioned in the documentation. 

In our workflow, we use that path to read the parquet files from outside (through databricks connector). Can we assume this path is reliable, or is it an "implementation detail" that might change at any time?

Yes, that link was also mentioned in my question. The point is if our pipeline can always assume that the path is where the parquet files for the managed tables are expected to be, or it's just an internal detail that could change at any time.

In our case we haven't configured or created the metastore directly. We're relying on the default metastore, which is where the tables are written when we do:

df.write.format("delta").mode("overwrite").saveAsTable(output_table_name)

I haven't found anything saying that the path of the default metastore might change unexpectedly. By the way, I don't even found something stating the opposite 🙂
