Hello Bryan, amazing content !
I have one question
df.write.mode('overwrite')..saveAsTable("df1") will not create a Delta Table right ?
It should be:
df.write.mode('overwrite').format("delta").saveAsTable("df1") ?
Am I missing something ?
The default file type is Delta according to this blog by Databricks docs.databricks.com/en/getting-started/dataframes.html See Step 5 Bear in mind, table means Delta table as that is the only file type that supports insert, delete, and update.
