Features

As a serverless event bus service, EG filters and routes events between multiple types of sources and targets.

Event Sources

Event sources are applications that produce events. EG supports the following event sources:

  • Huawei Cloud service: Elastic Cloud Server (ECS), Object Storage Service (OBS), Cloud Container Engine (CCE), and other services
  • Custom
    • Custom applications: connecting to EG via SDKs
    • DMS for RabbitMQ and DMS for RocketMQ

Event Targets

Event targets are destinations that receive and process events. EG supports the following event targets:

  • Huawei Cloud service : FunctionGraph and DMS for Kafka are supported.
  • Custom: HTTP and HTTPS Webhooks

Event Subscriptions

Subscriptions bind event sources, channels, and targets. Events of sources are routed to targets based on specified rules.

Event Streams

Event streams pull, filter, and transform events generated by event sources in real time for lightweight and efficient stream processing.

Resource Management

EG helps you manage the following resources:

  • Custom event sources
  • Event channels
  • Event subscriptions
  • Connections
  • Endpoints

Event Processing

EG provides the following event processing capabilities:

  • Transfer
  • Filtering
  • Routing

    EG processes each event separately. This means that the event processing order cannot be guaranteed, and in some cases, an event may be passed multiple times. Therefore, event processing programs must be idempotent.

Network Management

You can manage your connections and endpoints.

  • Connections: used to connect to Webhooks
  • Endpoints: used to push custom events

Event Monitoring

EG monitors event subscriptions and channels, and allows you to query event access and delivery information.
