You should visit Pricing - Pipedream for the latest pricing, but I’ll do my best to answer. It seems you’re using the AWS integration in Pipedream to stream files to S3, and you’re looking for an option to set the chunkSize. Unfortunately, the current S3 - Stream file to S3 from URL action does not provide an option to specify the chunkSize directly. If you need to customize the chunkSize, you might consider implementing a custom solution using a Node.js code step in Pipedream. This would involve manually handling the file streaming process and specifying the chunkSize as needed. If you need further assistance or have specific requirements, I recommend reaching out to Pipedream support at Support - Pipedream for more detailed guidance.
