WSO2 Streaming Integrator (SI) is a streaming data processing server that allows you to integrate streaming data and take action based on streaming data.
WSO2 SI can be effectively used for:
- Realtime ETL with files, DBs, SaaS apps, HTTP endpoints, etc.
- Working with streaming messaging systems such as Kafka and NATS.
- Streaming data integration
- Executing complex integrations based on streaming data with WSO2 Micro Integrator.
WSO2 SI is powered by Siddhi.io, a well-known cloud native open source stream processing engine. Siddhi lets users write complex stream processing logic using a SQL-like language known as SiddhiQL. You can aggregate, transform, enrich, analyze, cleanse and correlate streams of data on the fly using Siddhi queries and constructs.
WSO2 SI lets you connect to any data source with any destination regardless of different protocols and data formats that are used by different endpoints. The SI store API provides the capability to fetch stored and aggregated data kept in-memory and in DBs via a REST API on demand using ad-hoc queries.
SI tooling provides a web-based IDE that allows you to build Siddhi applications with a drag-and-drop graphical editor, or a streaming SQL code editor. Its capability to simulate data streams and to debug Siddhi queries facilitates you to test your Siddhi applications. Created Siddhi applications can be directly deployed in a VM via the IDE, exported as a Docker image, or deployed as K8s artifacts that can be used with the Siddhi K8s Operator.
SI has native support for Kubernetes with a K8s Operator designed to provide a convenient way of deploying SI on K8s. SI has a very simple deployment architecture, and you can achieve high availability with zero data loss with two nodes of SI.
Integration flows deployed in WSO2 Micro Integrator (MI) can be invoked directly by SI in a seamless manner using low latency RPC. This allows you to build robust data processing and integration pipelines by combining powerful streaming and integration capabilities.
