Our team members who are experienced with building highly available Apache Pulsar messaging platforms put together this video series that leads learners through installing, configuring, and running Pulsar. The course provides a critical foundation for how Pulsar, BookKeeper, and ZooKeeper work together, and provides all of the tools necessary for learners to start running Pulsar on their own. Pulsar Tutorial Curriculum Below is a list of the major themes / topics covered in this beginners course. The course also covers important subtopics such as security at rest and in transit for Pulsar, BookKeeper, and ZooKeeper; geo-replication; Pulsar functions; effectively once guarantees; and more.

NotesThe AoP plugin supports only the 0-9-1 protocol with basic produce and consume functionalities, and does not include advanced features such as transactions. It is available as an open-source plugin and is only offered as a private preview feature in the Private Cloud distribution as an experimental feature. It is not available on StreamNative Cloud. Please use it with caution.AMQP on Pulsar (AoP)AoP stands for AMQP on Pulsar. AoP broker supports AMQP0-9-1 protocol, and is backed by Pulsar.AoP is implemented as a Pulsar ProtocolHandler with protocol name "amqp". ProtocolHandler is built as a nar file, and is loaded when Pulsar Broker starts.LimitationsAoP is implemented based on Pulsar features. However, the methods of using Pulsar and using AMQP are different. The following are some limitations of AoP.Currently, the AoP protocol handler supports AMQP0-9-1 protocol and only supports durable exchange and durable queue.A Vhost is backed by a namespace which can only have one bundle. You need to create a namespace in advance for the Vhost.AoP is supported on Pulsar 2.6.1 or later releases.Get startedIn this guide, you will learn how to use the Pulsar broker to serve requests from AMQP client.Download PulsarDownload Pulsar 2.6.1 binary package apache-pulsar-2.6.1-bin.tar.gz. and unzip it.Download and Build AoP PluginYou can download aop nar file from the AoP releases.To build from code, complete the following steps:Clone the project from GitHub to your local.git clone aopBuild the project.mvn clean install -DskipTestsYou can find the nar file in the following directory../amqp-impl/target/pulsar-protocol-handler-amqp-${version}.narConfigurationNameDescriptionDefaultamqpTenantAMQP on Pulsar broker tenantpublicamqpListenersAMQP service portamqp://127.0.0.1:5672amqpMaxNoOfChannelsThe maximum number of channels which can exist concurrently on a connection64amqpMaxFrameSizeThe maximum frame size on a connection4194304 (4MB)amqpHeartBeatThe default heartbeat timeout of AoP connection60 (s)amqpProxyPortThe AMQP proxy service port5682amqpProxyEnableWhether to start proxy servicefalseConfigure Pulsar broker to run AoP protocol handler as PluginAs mentioned above, AoP module is loaded with Pulsar broker. You need to add configs in Pulsar's config file, such as broker.conf or standalone.conf.Protocol handler configurationYou need to add messagingProtocols(the default value is null) and protocolHandlerDirectory (the default value is "./protocols"), in Pulsar configuration files, such as broker.conf or standalone.conf. For AoP, the value for messagingProtocols is amqp; the value for protocolHandlerDirectory is the directory of AoP nar file.The following is an example.messagingProtocols=amqpprotocolHandlerDirectory=./protocolsSet AMQP service listenersSet AMQP service listeners. Note that the hostname value in listeners is the same as Pulsar broker's advertisedAddress.The following is an example.amqpListeners=amqp://127.0.0.1:5672advertisedAddress=127.0.0.1Run Pulsar brokerWith the above configuration, you can start your Pulsar broker. For details, refer to Pulsar Get started guides.cd apache-pulsar-2.6.1bin/pulsar standaloneRun AMQP Client to verifyLog level configurationIn Pulsar log4j2.yaml config file, you can set AoP log level.The following is an example. Logger: - name: io.streamnative.pulsar.handlers.amqp level: debug additivity: false AppenderRef: - ref: ConsoleAoP configurationThere is also other configs that can be changed and placed

Performance Created by DataStax to use best practices for database writes, resulting in fast data movement. Simple You have to write zero lines of code if you use the connector to ingest from Pulsar to a DataStax Luna Cassandra-as-a-Service, DataStax Enterprise or Apache OSS Cassandra database. DataStax Change Agent for Apache Cassandra (CAC) Package Change Agent for Apache Cassandra® is a Java-based agent that runs locally with each Cassandra node, capturing changes by inspecting the commit log, and publishing them to an Apache Pulsar topic. NoSQLBench Package NoSQLBench brings advanced testing capabilities into one tool that are not found in other testing tools. You can run common testing workloads directly from the command line. You can start doing this within 5 minutes of reading this. You can generate virtual data sets of arbitrary size, with deterministic data and statistically shaped values. You can design custom workloads that emulate your application, contained in a single file, based on statement templates — no IDE or coding required. You can immediately plot your results in a docker and grafana stack on Linux with a single command line option. When needed, you can open the access panels and rewire the runtime behavior of NoSQLBench to do advanced testing, including a full scripting environment with JavaScript. DataStax Cassandra Source Connector for Apache Pulsar (CSC) Package The Apache Cassandra® Source Connector for Apache Pulsar™ (CSC) is a Pulsar IO source connector that processes changes from the Cassandra Change Agent, via a Pulsar topic, deduplicates them and makes sure they are current and then publishes them to another topic for consumers to access. CSC works with Apache Pulsar, including the DataStax Luna Streaming distribution of Apache Pulsar. DataStax Starlight for RabbitMQ Package DataStax Starlight for RabbitMQ is a drop-in compatibility layer that allows your RabbitMQ applications to
