This tutorial shows how to convert delimited text files into Parquet format in Advanced ETL Processor. Use the Delimited File to Parquet action when row-based text files need to become columnar files for reporting, analytics, or data lake storage.
What You Will Learn
- Configure the Delimited File to Parquet action.
- Convert delimited text input into Parquet output.
- Review action metadata, parameters, variables, and execution logs.
- Use Parquet when downstream tools need columnar storage instead of CSV-style rows.
Before You Start
Use a test repository or safe sample data while following the tutorial. Production jobs are a poor place to experiment.
Delimited File To Parquet Action Docs
This tutorial uses the Delimited File to Parquet Dynamic Action to convert text data into Parquet. Parquet stores data by columns rather than rows, which is useful when analytics tools read only selected fields. CSV can do many things. Being columnar is not one of them.
The action documentation explains what Parquet is for, the metadata tab, and the parameters tab. Check the source delimiter, field handling, and output path before running the conversion unattended.
For repeat jobs, review the variables tab, the execution log tab, plus the related guides for debugging actions and working with variables.
