Stream Parquet File Reader

Learn more about the Stream Parquet File Reader connector and how to use it in the Digibee Integration Platform.

The Stream Parquet File Reader connector allows you to read Parquet files triggering subpipelines to process each message individually. This connector should be used for large files.

Parquet is a columnar file format designed for efficient data storage and retrieval. For more information, see the official website.

Parameters

Take a look at the configuration parameters of the connector. Parameters supported by Double Braces expressions are marked with (DB).

General Tab

Parameter	Description	Default value	Data type
File Name (DB)	The file name of the Parquet file to be read.	{{ message.fileName }}	String
Parallel Execution	Occurs in parallel with loop execution.	false	Boolean
Fail On Error	If the option is active, the execution of the pipeline with an error will be interrupted. Otherwise, the pipeline execution proceeds, but the result will show a false value for the “success” property.	false	Boolean

Documentation Tab

Parameter	Description	Default value	Data type
Documentation	Section for documenting any necessary information about the connector configuration and business rules.	N/A	String

A compressed Parquet file generates JSON content larger than the file itself when it is read. It is important that you checj whether the pipeline has enough memory to handle the data, as it will be stored in the pipeline's memory.

Usage examples

Reading Parquet file

• File Name: file.parquet

• Parallel: deactivated

Output:

{
	"total": 1000,
	"success": 1000,
	"failed": 0
}

If the lines have been processed correctly, their respective subpipelines return { "success": true } for each individual line.
