can we update a Parquet file??

[kkumar]

i have copied a table in to a Parquet file now can i update a row or a column in a parquet file without rewriting all the data as the data is huge.

using Databricks or ADF

Thank You

You can only append Data with Parquet that's why you need to convert your parquet table to Delta. It will be much easier.

Thank You for the reply.

True, but for a requirement, I was looking for a way to update a Parquet file.

I guess we cant.

correct. parquet files are immutable.
