Transports

Transports move data from one place to another – between acquisition programs and pipelines, between pipelines and the entity database, and even between pipelines and external systems.

Supported transports

CAP supports several transport methods:

• RabbitMQ
• Kafka
• Azure Service Bus
• Amazon SQS
• NATS
• In-Memory Queue
• Redis Streams
• Apache Pulsar
