Snowflake – Snowpipe Streaming

In this article

Overview

You can use this Snap to insert data into Snowflake using the Snowpipe Streaming API, which enables the continuous ingestion of data into Snowflake tables as and when it is available.

The Snowpipe Streaming Snap uses the role defined in the accounts' Url properties field. If a role is not defined, the Snap runs a SELECT CURRENT_ROLE() to determine a suitable role, failing which it falls back to the PUBLIC role.

Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the pipeline by choosing one of the following options from the When errors occur list under the Views tab:

  • Stop Pipeline Execution: Stops the current pipeline execution if the Snap encounters an error.

  • Discard Error Data and Continue: Ignores the error, discards that record, and continues with the remaining records.

  • Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution.

Learn more about Error handling in Pipelines.

Select this checkbox if you want the table to be automatically created if it does not already exist.

Max client lag*

 

Default Value1000
Example: 1500
Max Value: 60,000

Integer/Expression/Suggestion

Specify the client data flush interval in milliseconds. Adjust this value based on the maximum latency your target system can handle (60,000 ms).

This field also accepts inputs in n-second and n-minute formats. Maximum value is 10 minutes.

Snap execution

Default Value
Example: Validate & Execute

Dropdown list

Select one of the following three modes in which the Snap executes:

  • Validate & Execute: Performs limited execution of the Snap and generates a data preview during pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during pipeline runtime.

  • Execute only: Performs full execution of the Snap during pipeline execution without generating preview data.

  • Disabled: Disables the Snap and all Snaps that are downstream from it.
