AMQP client from AWS lambda that works with Solace
Hi, we would like to publish to Solace topic from AWS lambda ( written in java). Is there any java AMQP client library that we can use to do that ?
The Solace Broker supports AMQP 1.0, so as long as you're using a client library that works with v1.0 you should be fine. We usually see folks use the QPID library.
Note that if you're not already familiar with AMQP it can be confusing to get started so you might consider using a MQTT, JMS, or SMF library. From a Lambda function it might even make sense to use REST messaging as you may not need to include extra libraries. If you go to https://solace.dev, scroll down to "Connect Using a Supported Client Library" and choose "Java" you'll see some of the options available.
Hope that helps!0
Hey @rsingh81 - if everyone of those 50k records will be processed by an AWS Lambda function call, then you can publish each record separately from your lambda function. I am not sure how your lambda function architecture is setup but a batch approach could also work.
How are you processing your 50k records?0

Thanks @Tamimi, sorry it took so long to get back to this.
Our logic to call from AWS lambda is written in java
something like this
- Call to lambda Handler Function -> 2. Get all the records in one go to publish downstream -> 3.Calls Solace REST publishiser look something like this
My preference is to publish one records at a time, as then it can be more elegantly handled on the consumer side. I am bit concerned how will AWS lambda work underneath the hood when connecting to Solace broker i.e. if we perform step 3 above for each of the 50k record, I don't want to hog the available connections for the Solace pub/sub +. Would you be able to advise on this whether connections will be reused or created one for each record published to Http?0
