             Summary: Cassandra MailQueue implementation has a 20% fail rate on 
load
                 Key: JAMES-2605
                 URL: https://issues.apache.org/jira/browse/JAMES-2605
             Project: James Server
          Issue Type: Bug
          Components: cassandra
            Reporter: Matthieu Baechler


RabbitMQ + Cassandra implementation of Mailqueue proved to be brittle, we have 
around 20% error rate for SMTP mail delivery under heavy load.

It's probably linked to the heavy use of parallelism into Cassandra Mailqueue 
code that can submit an unbounded numer of request for a single Mailqueue 
operation.

 

We should try to remove this unbounded parallelism and check the failure rate 
under load.
