jcustenborder / flume-ng-rabbitmq Goto Github PK

I'm not sure if I'm missing something but I'm only able to pull somewhere between 10-50 messages/second from my RMQ source but I'm able to get in the range of several thousand per second by pulling directly from RMQ or using other RMQ plugins. Any thoughts? Thanks.

You use 'queuename' to define the 'routingkey' in RabbitMQ sink

I found that in situations where the _Connection and _Channel are reset (and set to null), the _Consumer is not also getting reset. For me this caused a loop in connectionReset after _Consumer.nextDelivery(). Resetting the _Consumer when the _Channel is recreated solved this for me. If I find the time to learn github pull requests, I may submit my code, but it's pretty straightforward (single line).

Consumer reports an error during consuming rabbit messages, but the exception handling mechanism went into infinite recursion loop.

Recursion look is caused by below code: (RabbitMQSource.java line 176)

@Override protected void doStop() throws FlumeException { RabbitMQUtil.close(_Connection, _Channel); super.stop(); }

Where super.stop(); will call doStop internally.

As the title, I have seen the RabbitMQConstants.java
