You can use this Snap to interact with a gRPC (Google Remote Procedure Call) server to invoke its services. gRPC is a high-performance, open-source framework developed by Google that uses protocol buffers (Protobuf) as its interface definition language (IDL) to define the structure of the service and the messages exchanged between the client and server.

Example:

String/Expression

Specify the server to which the requests are sent.

gRPC service


Default Value: N/A

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 based on Preview Document Count value in User settings 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.

Troubleshooting

Error

Reason

Resolution

Account validation failed.

The Pipeline ended before the batch could complete execution due to a connection error

  • .

Verify that the Refresh token field is configured to handle the inputs properly. If you are not sure when the input data is available, configure this field as zero to keep the connection always open.

Examples

Excluding Fields from the Input Data Stream

We can exclude the unrequired fields from the input data stream by omitting them in the Input schema fieldset. This example demonstrates how we can use the <Snap Name> to achieve this result:
