NATS Get message by id

[Dana Keydar]

Hi all,

Is there any way to get an existing message by id ? 

Tnx.

Not at this time, only by sequence number, or last for subject, or next for subject with a given starting sequence number.

Hi Derek,

Thanks foe the quick response!

I realized each message has unique sequence number right? and when publishing a message  I can keep this sequence number and later get this specific message using the sequence number?

If so , how can I do it? I didn't find any examples of it.

Yes that is correct.

For admin purposes most clients allow you to get the message directly from the stream.

In the next release their is a more highly optimized version to support the KV materialized views.
