Solace Message Compression

PubSub+ Event Broker
1

Hi Team,
I need some help with solace message compression.In our solace broker the maximum message size is configured as 10MB.So I used the below property to compress the message :
message.setIntProperty(SupportedProperty.SOLACE_JMS_COMPRESSION_LEVEL, 9);
As of now we don’t have a specific broker to publish compressed message.So is there any way we can compress the message and publish to solace.

Hi @Monali,
Message compression is only about compression during transfer (that is between your client and the broker).
In the broker itself, the message is always un-compressed - and therefor the uncompressed message size is relevant for maximum message size.
You can compress your payload on publisher side and un-compress on consumer side, but this is outside the Solace API.

And to answer the question: “Why does the broker handle only uncompressed messages ?”
Solace broker do protocol translation - and some clients have compressed SMF as protocol, some clients have uncompressed REST or uncompressed MQTT …
The only way to handle that fast with low latency is to handle only uncompressed messages.

Thanks @uherbst for responding so quickly
“You can compress your payload on publisher side and un-compress on consumer side, but this is outside the Solace API.”
We are using sol-jms api,may be my question would be very basic but have few queries on the same:
So I can compress the payload using GZIP and publish the message as BytesMessage.Can we proceed with such approach.

yes, that was exactly what I had in my mind.
