Hello,
I want to compress the messages I'm sending to ARTEMIS 2.15.0. The messages are
roughly speaking 9MB big and are sent using a JMS TextMessage instance.
To do so I have created an instance of org.apache.qpid.jms.JmsConnectionFactory
using this URL
amqp://localhost:5672?messageCompressionThresholdSize=5000&compressMessages=true
JmsConnectionFactory qpidFactory = new
JmsConnectionFactory("amqp://localhost:5672?messageCompressionThresholdSize=5000&compressMessages=true");
...
When I'm producing messages using this factory, the messages are not compressed.
Where did I go wrong ?

The Qpid JMS client does not support any sort of message compression so
I'm guessing you got those URI options from some Artemis Core (JMS)
client documentation which explains why they don't produce any
compressed output by the client.
Performing message compression from within a client is often bound to
cause issues due to the need for every intermediary within the
transmission chain that might need to touch the message to understand
what kind of compression is used if any and how to decompress and then
compress again depending on transformations etc. Issues can arise for
instance when crossing between the various protocol clients that might
be consuming messages from the Artemis broker.
The best strategy here might be for you to use a BytesMessage as your
means of sending they bytes that you compress yourself so that you can
control the decompression on the receiving ends as needed.
