A message broker system ensures data consistency by providing uniform message delivery and reception, tackling the challenges posed by system failures, duplicates, and missed messages.
Techniques for maintaining data consistency include replication for data accessibility across brokers and implementing consensus protocols like Paxos or Raft for agreement on system state.
A reliable message broker system must exhibit self-healing capabilities, utilizing failover mechanisms to switch to standby brokers and health checks to monitor the system's status.
To support growing demands effectively, scalability in a message broker system can be achieved through horizontal scaling, allowing the addition of more brokers to handle increased load.
