The Amazon Web Services (AWS) SQS output in ArcGIS Velocity allows you to write output features or values created using Arcade to Amazon Simple Queue Service (SQS). You can then send, store, and receive messages between software components. Velocity uses the Amazon SQS output to integrate and decouple distributed applications.
Example
Ниже приводится пример использования выходных данных:
A data analyst wants to export features from a certain Velocity pipeline to Amazon SQS to integrate with either a serverless application or a distributed system.
Usage notes
При работе с выходными данными нужно учитывать следующее:
The secret key is encrypted the first time the analytic is saved, and it is stored in an encrypted state.
The following output data formats are available:
- Delimited
- JSON
- GeoJSON
- EsriJSON
Примечание:
Alternatively, you can configure an Arcade expression to control the message sent to Amazon SQS.
Data exported in the JSON format provides geometry in the EsriJSON format.
- Certain Amazon SQS actions are required for your user policy associated with the specified Amazon key for Velocity to connect and write to an Amazon SQS queue.
