Unable to create a record_id column via DLT - Autoloader

Valued Contributor

Hi Community,

I'm trying to load data from the landing zone to the bronze layer via DLT- Autoloader, I want to add a column record_id to the bronze table while I fetch my data. I'm also using file arrival trigger in the workflow to update my table incrementally.

I've followed a post in the community forum using monotonically_increasing_id() but it's not supported in the streaming use case. I also do not have any event-time based column to enable watermarking.

Attaching code snippet for reference:


def create_bronze_tables(
    def create_sample_tables():
        table = (
            .option("cloudFiles.format", "csv")
            .option("inferColumnTypes", True)
            .option("delimiter", "\t")
            .option("mergeSchema", "true")
            .withColumn("record_id", row_number().over(
        return table


the error I face is attached.

Any help in how to create a record-id in this setting is appreciated.
