Glossary of terms

Amazon SQS

Amazon Simple Queue Service (Amazon SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications.

Queue

A queue is a temporary repository for messages that are awaiting processing.

Message

A message is a unit of data that is sent from a sender to a receiver via a queue.

Sender

A sender is an application or service that sends messages to a queue.

Receiver

A receiver is an application or service that receives messages from a queue.

Dead Letter Queue

A dead letter queue is a queue that holds messages that cannot be processed successfully.

Visibility Timeout

The visibility timeout is the amount of time that a message is invisible in a queue after it is received from a receiver.

Long Polling

Long polling is a technique used to reduce the number of empty responses by allowing the queue to wait until a message is available before sending a response.

FIFO Queue

A FIFO (First-In-First-Out) queue is a queue that preserves the order in which messages are sent and received.

Standard Queue

A standard queue is a queue that supports a nearly unlimited number of transactions per second (TPS) and can be used for any application that requires high throughput.

Delay Queue

A delay queue is a queue that delays the delivery of messages for a specified amount of time.

Message Group

A message group is a set of related messages that are processed in order.

Message Batching

Message batching is a technique used to reduce the number of requests sent to a queue by combining multiple messages into a single request.

Message Deduplication

Message deduplication is a technique used to ensure that duplicate messages are not processed by a queue.

Message Filtering

Message filtering is a technique used to ensure that only messages that match certain criteria are processed by a queue.

Message Timestamps

Message timestamps are used to track when a message was sent and received.

Message Attributes

Message attributes are used to provide additional information about a message.

Message Retention Period

The message retention period is the amount of time that a message is retained in a queue before it is deleted.

Message Visibility

Message visibility is the amount of time that a message is visible in a queue after it is received from a receiver.

Message Redrive Policy

A message redrive policy is used to specify how messages that cannot be processed successfully are handled.

Message Acknowledgement

Message acknowledgement is a technique used to confirm that a message has been processed successfully.

Message Delivery Policy

A message delivery policy is used to specify how messages are delivered to receivers.

Message Throttling

Message throttling is a technique used to limit the rate at which messages are sent to a queue.

Message Prioritization

Message prioritization is a technique used to ensure that important messages are processed first.

Message Duplication

Message duplication is a technique used to ensure that a message is processed multiple times.

Message Expiration

Message expiration is the amount of time that a message is retained in a queue before it is deleted.

Message Queue

A message queue is a service that stores and delivers messages between applications or services.

Message Queueing

Message queueing is a technique used to ensure that messages are delivered reliably and in the correct order.

Message Routing

Message routing is a technique used to ensure that messages are delivered to the correct receiver.

Message Transformation

Message transformation is a technique used to convert messages from one format to another.

Message Validation

Message validation is a technique used to ensure that messages are valid before they are processed.

Queue Policies

Queue policies are used to control access to a queue.

Queue Tags

Queue tags are used to categorize queues.

Queue URLs

Queue URLs are used to identify queues.

Queue Size

Queue size is the number of messages in a queue.

Queue Depth

Queue depth is the number of messages that can be stored in a queue.

Queue Visibility

Queue visibility is the amount of time that a queue is visible to receivers.

Queue Lifecycle

The queue lifecycle is the amount of time that a queue is retained before it is deleted.

Queue Encryption

Queue encryption is a technique used to ensure that messages are encrypted while in transit.

Queue Monitoring

Queue monitoring is a technique used to track the performance of a queue.

Queue Logging

Queue logging is a technique used to track the activity of a queue.

Queue Management

Queue management is the process of creating, configuring, and managing queues.

Queue Security

Queue security is a technique used to ensure that messages are secure while in transit.

Queue Throttling

Queue throttling is a technique used to limit the rate at which messages are sent to a queue.

Queue Replication

Queue replication is a technique used to ensure that messages are delivered reliably and in the correct order.

Queue Sharding

Queue sharding is a technique used to distribute messages across multiple queues.

Queue Clustering

Queue clustering is a technique used to ensure that messages are delivered reliably and in the correct order.

Queue Load Balancing

Queue load balancing is a technique used to ensure that messages are evenly distributed across multiple queues.

Queue Scaling

Queue scaling is a technique used to ensure that queues can handle increased load.

Queue Optimization

Queue optimization is a technique used to improve the performance of a queue.

Queue Performance

Queue performance is the amount of time it takes for a queue to process messages.

Queue Availability

Queue availability is the amount of time that a queue is available for use.

Queue Durability

Queue durability is the ability of a queue to survive system or application failures.

Queue Latency

Queue latency is the amount of time it takes for a message to be delivered from a sender to a receiver.
