Feature

Description

Extremely High Performant Processing Engine

  • Process about 100K+ events per second on single-server commodity hardware
  • Powered by WSO2 Siddhi

Powerful and Extensible Query Language for Temporal Event Stream Processing

  • SQL-like query language
  • Filters events by conditions
  • Creates new event streams by merging existing event streams
  • Executes temporal queries using various windows
  • Detects and responds to various event patterns and sequences
  • Instigates with In-Memory and RDBMS data stores for correlating historical data with real-time
  • Partitioning support to achieve parallel processing
  • Maintenance of execution plan templates
User-friendly Execution Management
  • Suitable for business users to edit and manage realtime execution logic
  • Users interact with forms instead of with SQL Queries 
  • Queries and logics are templated to hide the complexity

Support for Rich Event Model

  • Events are modelled as tuples of metadata, correlation data and payload data.
  • Support for different property types including integral types, floating types, string and Boolean

Extremely High Performant Event Capturing and Delivery Framework Over Binary and Apache Thrift

  • Java data publisher agent to plug into any Java based system
  • Data publisher agent support in other languages (C/C++/C#) via Thrift language bindings
  • Horizontally scalable to support very large event volumes

Easily Integrates with any Enterprise System for Event Capture

  • RESTful HTTP protocol with JSON, XML and Text message formats
  • Map, JSON, XML and Text messages support via JMS
  • SOAP over any transport protocol
  • Kafka, MQTT, File, Websocket and Email protocols with JSON, XML and Text messages

Supports Multiple Alert Nitrifying Mechanisms

  • XML, JSON, Map, Text events via JMS protocol
  • E-mail, SMS notifications
  • Service calls to notify RESTful and Web services
  • MySQL and Cassandra writers
  • Kafka, MQTT, File, Websocket protocols supporting JSON, XML and Text messages alerts
IoT (Internet of Things) Integration
  • MQTT protocol
Debugging Support
  • Event tracing, Event Flow visualization and Event Simulation capabilities
  • Siddhi TryIt to try out Siddhi queries

Massively Scalable

  • Distributed Real Time Processing
  • Support highly scalable deployments with Apache Storm and WSO2 Siddhi 
  • Deploys numbers of queries partitioning them into different servers

Highly Available Deployment

  • Run CEP in active-passive deployment with zero downtime
  • Coordinates event and state sharing

Support for Long Duration Queries

  • Queries can have lifetimes that are much greater than server uptime
  • Supported via HA deployment and persistence snapshot deployment
  • Support periodic snapshots that can store all state information and windows to a scalable persistence store
  • Pluggable persistent stores

Tightly Integrates with WSO2 Data Analytics Server

  • Leverage Lambda architecture to integrate post-processed data with real-time data processing
  • Supports recording and post processing of events with Map-Reduce via Apache Spark

Built-in Support for WSO2 Products

  • Pre-built event sources from other WSO2 products

Lightweight, Developer Friendly and Easy to Deploy

  • Server customization via provisioning of features
  • Deployment options from on-premise to private or public clouds, without configuration changes
  • Integrated with WSO2 Developer Studio, the Eclipse-based IDE for all WSO2 products

Manage and Monitor

  • Comprehensive management and monitoring Web console with enterprise-level security
  • Built-in collection and monitoring of standard access and performance statistics
  • Flexible logging support with integration to enterprise logging systems
  • In build support for rich representation of data via a dashboard
  • Simulating capabilities via the Event Simulator.
  • No labels
