ChunJun (formerly FlinkX) is a distributed, batch-and-stream data integration framework built on Apache Flink. It synchronizes and computes data across 20+ heterogeneous data sources using configurable JSON templates or Flink SQL-compatible scripts, with a pluggable reader/writer/lookup architecture.
Use cases
- sync data between mysql and hive
- real-time cdc collection from relational databases
- incremental data synchronization between heterogeneous sources
- run flink sql based etl jobs on yarn or kubernetes
- migrate data between oracle and sqlserver
- store and monitor dirty data during sync jobs
- resume failed data sync tasks from checkpoints
When to choose
- you need batch and streaming data sync in one framework on Flink
- you must move data across many different databases and storage systems
- you want Flink SQL-compatible task configuration
- you need checkpoint-based resumable sync and dirty data handling
When to avoid
- you need a lightweight single-node ETL tool without a Flink cluster
- your data sources are not among the supported plugins and you cannot write Java plugins
- you want a fully managed cloud ETL service rather than self-operated infrastructure
