抄袭例证 1：
https://github.com/kwai/blaze/blob/master/native-engine/datafusion-ext-commons/src/spark_hash.rs
https://github.com/apache/datafusion-comet/blob/main/core/src/execution/datafusion/spark_hash.rs

抄袭例证 2：
https://github.com/kwai/blaze/blob/master/native-engine/blaze-jni-bridge/src/jni_bridge.rs#L1102
https://github.com/apache/datafusion-comet/blob/383ae9197422da5948a31caf21722569ef2067fe/core/src/jvm_bridge/comet_metric_node.rs#L28

抄袭例证 3：
https://github.com/kwai/blaze/blob/580bfe604d14604bdf3feb64b3368ba7faba5750/native-engine/datafusion-ext/src/shuffle_writer_exec.rs#L450
https://github.com/apache/datafusion-comet/blob/main/core/src/execution/datafusion/shuffle_writer.rs#L888

Blaze 就挂在 kwai 的名下，非常的显眼。

datafusion-comet 虽然表面看不出是 Apple 的开源代码，但实际上第一个提交的人里包含了全部都是 @Apple 的邮箱

The Blaze accelerator for Apache Spark leverages native vectorized execution to accelerate query processing. It combines the power of the Apache Arrow-DataFusion library and the scale of the Spark distributed computing framework.

Apache DataFusion Comet is an Apache Spark plugin that uses Apache DataFusion as native runtime to achieve improvement in terms of query efficiency and query runtime.
