RabbitMQ Quorum Queues replace classic mirrored queues with Raft consensus for stronger durability and predictable failover. Learn the trade-offs in throughput, the 3-node requirement, and how to migrate.
A cross-tablet transaction in YugabyteDB cannot commit on one disk. This architecture note explains how Raft groups, leaseholders, and a two-phase commit variant preserve atomicity, what to inspect with yb-admin, and when clock skew or hotspotting changes the design.

Stop relying on deprecated mirrored queues. Learn how RabbitMQ Quorum Queues use the Raft consensus algorithm to provide strong data durability and how to implement them with publisher confirms.
Architecture note for YugabyteDB synchronous multi-AZ deployment: 3-node RF=3 design, Raft quorum boundaries, operational metrics, failure modes, and triggers for design changes (async xCluster, follower reads, placement policies).
RabbitMQ 4.0 removed classic mirrored queues. Quorum queues use Raft consensus for stronger durability, but require 3+ nodes, more disk I/O, and a migration strategy since in-place conversion isn't supported.
An architecture note on the smallest YugabyteDB cluster worth running: three nodes, three zones, RF 3, with tablets as Raft groups. Covers placement flags, operational checks, and the failure modes that should trigger a redesign.
Decision guide for RabbitMQ high-availability: compare Classic Mirrored vs. Quorum queues, analyze Raft-based consistency trade-offs, and validate automatic failover.
Learn how to balance performance and consistency in YugabyteDB by choosing between Strong Global Consistency and Snapshot Isolation for distributed workloads.
