Chapter 1. Overview AMQ Python is a library for developing messaging applications. It enables you to write Python applications that send and receive AMQP messages. AMQ Python is part of AMQ Clients, a suite of messaging libraries supporting multiple languages and platforms. For an overview of the clients, see AMQ Clients Overview . For information about this release, see AMQ Clients 2.9 Release Notes . AMQ Python is based on the Proton API from Apache Qpid . For detailed API documentation, see the AMQ Python API reference . 1.1. Key features An event-driven API that simplifies integration with existing applications SSL/TLS for secure communication Flexible SASL authentication Automatic reconnect and failover Seamless conversion between AMQP and language-native data types Access to all the features and capabilities of AMQP 1.0 Distributed tracing based on the OpenTracing standard (RHEL 7 and 8) Important Distributed tracing in AMQ Clients is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For more information about the support scope of Red Hat Technology Preview features, see https://access.redhat.com/support/offerings/techpreview/ . 1.2. Supported standards and protocols AMQ Python supports the following industry-recognized standards and network protocols: Version 1.0 of the Advanced Message Queueing Protocol (AMQP) Versions 1.0, 1.1, 1.2, and 1.3 of the Transport Layer Security (TLS) protocol, the successor to SSL Simple Authentication and Security Layer (SASL) mechanisms supported by Cyrus SASL , including ANONYMOUS, PLAIN, SCRAM, EXTERNAL, and GSSAPI (Kerberos) Modern TCP with IPv6 1.3. Supported configurations AMQ Python supports the OS and language versions listed below. For more information, see Red Hat AMQ 7 Supported Configurations . Red Hat Enterprise Linux 7 with Python 2.7 Red Hat Enterprise Linux 8 with Python 3.6 Microsoft Windows 10 Pro with Python 3.6 and Python 3.8 Microsoft Windows Server 2012 R2 and 2016 with Python 3.6 and Python 3.8 AMQ Python is supported in combination with the following AMQ components and versions: All versions of AMQ Broker All versions of AMQ Interconnect A-MQ 6 versions 6.2.1 and newer 1.4. Terms and concepts This section introduces the core API entities and describes how they operate together. Table 1.1. API terms Entity Description Container A top-level container of connections. Connection A channel for communication between two peers on a network. It contains sessions. Session A context for sending and receiving messages. It contains senders and receivers. Sender A channel for sending messages to a target. It has a target. Receiver A channel for receiving messages from a source. It has a source. Source A named point of origin for messages. Target A named destination for messages. Message An application-specific piece of information. Delivery A message transfer. AMQ Python sends and receives messages . Messages are transferred between connected peers over senders and receivers . Senders and receivers are established over sessions . Sessions are established over connections . Connections are established between two uniquely identified containers . Though a connection can have multiple sessions, often this is not needed. The API allows you to ignore sessions unless you require them. A sending peer creates a sender to send messages. The sender has a target that identifies a queue or topic at the remote peer. A receiving peer creates a receiver to receive messages. The receiver has a source that identifies a queue or topic at the remote peer. The sending of a message is called a delivery . The message is the content sent, including all metadata such as headers and annotations. The delivery is the protocol exchange associated with the transfer of that content. To indicate that a delivery is complete, either the sender or the receiver settles it. When the other side learns that it has been settled, it will no longer communicate about that delivery. The receiver can also indicate whether it accepts or rejects the message. 1.5. Document conventions The sudo command In this document, sudo is used for any command that requires root privileges. Exercise caution when using sudo because any changes can affect the entire system. For more information about sudo , see Using the sudo command . File paths In this document, all file paths are valid for Linux, UNIX, and similar operating systems (for example, /home/andrea ). On Microsoft Windows, you must use the equivalent Windows paths (for example, C:\Users\andrea ). Variable text This document contains code blocks with variables that you must replace with values specific to your environment. Variable text is enclosed in arrow braces and styled as italic monospace. For example, in the following command, replace <project-dir> with the value for your environment: USD cd <project-dir>

Commands:
cd <project-dir>
