Yandex Message Queue
A queue service for messaging between components of distributed applications and microservices.
Standard and FIFO queues
Compatibility with the Amazon SQS HTTP API
Fast processing
Secure message storage
Integration with functions and triggers
Implement your projects using Message Queue
Application scalability
Use the message queue to scale your system of standalone applications and services. When the process of sending and handling messages runs smoothly, you can change the number of applications without affecting the rest of the system.
Improved fault tolerance
If an application fails to handle a message, the message is returned to the queue and can be read by another handler. You can also set up a Dead Letter Queue (DLQ), a queue for messages that consumers couldn’t process in standard queues.
Perform resource-intensive tasks
With message queuing, you can move long-running tasks to separate applications and free up resources for new user requests faster.
Questions and answers
How do standard queues handle messages?
Consumers read messages from a standard queue in random order. Standard queues guarantee that each message is delivered at least once. In rare cases, a message can be received from a standard queue twice. Use standard queues when you need maximum throughput.

What is the difference between FIFO and standard queues?
Messages are read from a FIFO queue in the order that they are received. FIFO queues guarantee exactly-once delivery, but their throughput is limited to 30 messages per second. Use FIFO queues if you need strictly ordered message delivery and exactly-once processing.
