difference between DeliveryMode.PERSISTENT and durable queue

[merkava]

Hi guys

What is the differnce between DeliveryMode.PERSISTENT(which is configured when sending message) and durable queue(which is defined in config file)?

I mean what is result of mixing these two options?

1. persistant message , durable queue

2. persistant message , non durable queue

3. nonpersisted message , durable queue

4. nonpersisted message , non durable queue

In which case message will be persisted?

which one have the most throughput and performance?

2. persistant message , non durable queue

3. nonpersisted message , durable queue

4. nonpersisted message , non durable queue

1. persisted

2. non persisted

3. non persisted

4. non persisted

which one have the most throughput and performance?

4, even tho 2 and 3 dont have the over head of writing to disc there are different send acknowledge semantics which slow down the send rate (with default configuration)
