Apache Celeborn is an elastic, high-performance intermediate data service for big data compute engines, focused on managing shuffle and spilled data. It decouples compute from storage of intermediate data via a Master/Worker architecture with push-based shuffle write and merged shuffle read.
Use cases
- speed up spark shuffle in large clusters
- replace spark external shuffle service
- manage shuffle data for flink jobs
- reduce shuffle failures and straggler tasks in mapreduce
- disaggregate compute and shuffle storage
- stabilize etl pipelines with heavy shuffle
When to choose
- you run large-scale Spark, Flink, or Hadoop MapReduce workloads with heavy shuffle
- you need elastic, fault-tolerant shuffle management separated from compute nodes
- you want push-based shuffle to improve stability and performance
When to avoid
- your workloads are small and local shuffle works fine
- you cannot operate an additional Master/Worker cluster service
- you use engines other than Spark, Flink, or MapReduce
