What would you like to happen?

Create a NATS JetStream IO connector with a Read transform for consuming messages and a Write transform for producing messages.

Features in a first iteration:

Read

• Read messages from a subject in a stream with an existing durable consumer
• Allow the user to configure watermark estimation based on publishing time or processing time
• Deduplicate messages based on message ID

Write

• Write messages to a subject in a stream
• Rely on the NATS server built-in deduplication of messages based on message ID
