6.6.3. Replication Queue Usage

When using the replication queue, do one of the following:
  • Disable asynchronous marshalling; or
  • Set the max-threads count value to 1 for the transport executor. The transport executor is defined in standalone.xml as follows: 
    <transport executor="infinispan-transport"/>
    Copy to Clipboard Toggle word wrap
To implement either of these solutions, the replication queue must be in use in asynchronous mode. Asynchronous mode can be set, along with the queue timeout (queue-flush-interval, value is in milliseconds) and queue size (queue-size) as follows: 
<replicated-cache name="asyncCache" 
                  start="EAGER"
                  mode="ASYNC"
                  batching="false"
                  indexing="NONE"
                  queue-size="1000"
                  queue-flush-interval="500">   
               ...
</replicated-cache>
Copy to Clipboard Toggle word wrap
The replication queue allows requests to return to the client faster, therefore using the replication queue together with asynchronous marshalling does not present any significant advantages.
