Apache Gluten is a middle-layer plugin that offloads JVM-based SQL engine execution (primarily Spark SQL) to high-performance native engines like Velox and ClickHouse. It translates Spark physical plans into Substrait plans executed natively via JNI, delivering up to 3x+ speedups with zero changes to user queries or DataFrame code.
Use cases
- accelerate spark sql queries without changing application code
- speed up etl pipelines running on spark
- offload jvm sql execution to native vectorized engines
- run tpc-h and tpc-ds benchmarks faster on spark
- switch between velox and clickhouse backends for spark workloads
- add columnar shuffle and columnar processing to spark
- reduce compute cost of petabyte-scale spark jobs
When to choose
- you run Spark SQL workloads and want major performance gains without rewriting queries
- your bottleneck is per-operator execution performance rather than query planning
- you want to leverage native engines like Velox or ClickHouse while keeping the Spark ecosystem
- you need automatic fallback to vanilla Spark for unsupported operators
When to avoid
- you don't use a JVM-based SQL engine like Spark
- your queries rely heavily on operators unsupported by the native backends, causing frequent fallback
- you cannot enable off-heap memory or add Spark plugins in your environment
- you need a lightweight solution and can't tolerate the added operational complexity of native bundle JARs
