Client Side Tuning Parameters

Given below are a list of tuning parameters which you need to configure at the client side. 

maxAckWaitTimeOut

Parameter
System Property - AndesAckWaitTimeOut
DescriptionWhen delivering queue messages to subscriptions, MB reads messages from the Cassandra store, and deliver them to the Andes Client. These messages are buffered at the client side. Client side application get messages from this buffer. Client side application should acknowledge the message it got from this buffer within the configured time with this parameter. If it failed to acknowledge within this time client informs MB sever that this message was rejected from the client. Then the message will be scheduled to be redelivered later by the server. There is a maximum times a message can be rejected by the client and redelivered (which is governed by the parameter here). Set this value in milliseconds.
