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

Input[Data Source Input] -> Filter[Data Processing] -> Output[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.

Plugins supported by SeaTunnel  

• Input plugin Fake, File, Hdfs, Kafka, S3, Socket, self-developed Input plugin

• Filter plugin Add, Checksum, Convert, Date, Drop, Grok, Json, Kv, Lowercase, Remove, Rename, Repartition, Replace, Sample, Split, Sql, Table, Truncate, Uppercase, Uuid, Self-developed Filter plugin

• Output plugin Elasticsearch, File, Hdfs, Jdbc, Kafka, Mysql, S3, Stdout, self-developed Output plugin

Environmental dependency

1. java runtime environment, java >= 8

2. 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.
