Event-streaming development platform based on Apache Pulsar

Function Stream

Function stream is a distributed event-driven application development platform based on Apache Pulsar. The goal is to facilitate the development of streaming applications for users. Function Stream providing more convenience for the development of distributed event-driven applications based on the existing features provided by the pulsar function.

Users can manage Pulsar Functions through this platform, including creating, editing, and deleting functions, and also provides management of function image files. Function Stream will make many extensions on the basis of the Pulsar Function to make it more convenient for users to develop distributed event-streaming application. In future plans, the online code editing feature and workflow editing feature will also be added.

Install

Install Apache Pulsar

Function Stream uses Apache Pulsar as the underlying messaging and processing engine, relying heavily on pulsar's features. Before we set up the function stream, we need to install apache pulsar.

• Download the modified version pulsar server package from here.
• You can skip this step if just want to start the pulsar proxy with default config. Configure conf/proxy.conf as below:

# The ZooKeeper quorum connection string (as a comma-separated list)
zookeeperServers=localhost

# Configuration store connection string (as a comma-separated list)
configurationStoreServers=localhost

# if Service Discovery is Disabled this url should point to the discovery service provider.
brokerServiceURL=localhost

# The port to use for server binary Protobuf requests
servicePort=3001

# Port that discovery service listen on
webServicePort=3000

• Start pulsar standalone with the command: bin/pulsar standalone -nss.
• Start pulsar proxy with the command: bin/pulsar proxy.
