Can I convert parquet files to Delta?

User16826992666 — Thu, 17 Jun 2021 02:57:27 GMT

I am already storing my data as parquet files and have registered them as a table in Databricks. If I want to convert the table to be a Delta table, do I have to do a full read of the data and rewrite it in the Delta format?

We can convert Parquet table to Delta using below command

CONVERT TO DELTA <table_name>

CONVERT TO DELTA parquet.<location>

its better to provide table name so that metastore also gets updated, also it would be good idea to avoid update/insert new data while converting to Delta.
