Output file naming conventions

This section describes the supported file naming conventions for data delivery and ingestion.

Use the following filename patterns:

CSV files: HERE_DA_*.csv.gz
Example: HERE_DA_XXXXXX_00000.csv.gz
Parquet files: part-*.gz.parquet
Example: part-00000-acab3571-4e00-4f66-8e4f-dd87c218b3a5-c000.gz.parquet

Avoid generic patterns such as *.csv or *.parquet. These patterns may match unintended files if the folder contains additional content.

For reliable, scalable, and production-ready data pipelines, use:

  • A stable folder structure
  • A defined filename pattern
  • A consistent schema
