Apache SeaTunnel (Incubating)

SeaTunnel was formerly named Waterdrop , and renamed SeaTunnel since October 12, 2021.

SeaTunnel is a very easy-to-use ultra-high-performance distributed data integration platform that supports real-time synchronization of massive data. It can synchronize tens of billions of data stably and efficiently every day, and has been used in the production of nearly 100 companies.

Why do we need SeaTunnel

SeaTunnel will do its best to solve the problems that may be encountered in the synchronization of massive data:

Data loss and duplication
Task accumulation and delay
Low throughput
Long cycle to be applied in the production environment
Lack of application running status monitoring

SeaTunnel use scenarios

Mass data synchronization
Mass data integration
ETL with massive data
Mass data aggregation
Multi-source data processing

Features of SeaTunnel

Easy to use, flexible configuration, low code development
Real-time streaming
Offline multi-source data analysis
High-performance, massive data processing capabilities
Modular and plug-in mechanism, easy to extend
Support data processing and aggregation by SQL
Support Spark structured streaming
Support Spark 2.x

Workflow of SeaTunnel

Source[Data Source Input] -> Transform[Data Processing] -> Sink[Result Output]

The data processing pipeline is constituted by multiple filters to meet a variety of data processing needs. If you are accustomed to SQL, you can also directly construct a data processing pipeline by SQL, which is simple and efficient. Currently, the filter list supported by SeaTunnel is still being expanded. Furthermore, you can develop your own data processing plug-in, because the whole system is easy to expand.

Environmental dependency

java runtime environment, java >= 8
If you want to run SeaTunnel in a cluster environment, any of the following Spark cluster environments is usable:

Spark on Yarn
Spark Standalone

If the data volume is small, or the goal is merely for functional verification, you can also start in local mode without a cluster environment, because SeaTunnel supports standalone operation. Note: SeaTunnel 2.0 supports running on Spark and Flink.
