Hello everyone, From a list of folders on s3, how can I identify from Databricks which ones are Delta tables which are not?

if they have a sub-folder called

_delta_log

it is very likely a Delta Lake table

Got it, thanks!

You can use dbutils.fs.ls to look at the file types inside the folders. There is nothing in a folder name that would indicate if it has a file in it let alone what kinds of files

The isDeltaTable class method might be useful.

DeltaTable.isDeltaTable(spark, "/path/to/table")

Good one @Matthew Powers! Thanks a lot!
