SQL INSERT File Format

This file format contains an INSERT...VALUES statement to be executed on the destination during the load stage.

Additional data types are stored as follows:

  • datetime and date are stored as ISO strings;
  • decimal is stored as a text representation of a decimal number;
  • binary storage depends on the format accepted by the destination;
  • complex storage also depends on the format accepted by the destination.

This file format is compressed by default.

Supported Destinations

This format is used by default by: DuckDB, Postgres, Redshift.

It is also supported by: filesystem.

By setting the loader_file_format argument to insert_values in the run command, the pipeline will store your data in the INSERT format at the destination:

info =, loader_file_format="insert_values")
