-------------------------------------
Summary: Support tensor type (TensorType) in Spark SQL/DataFrame
Key: SPARK-31775
URL: https://issues.apache.org/jira/browse/SPARK-31775
Project: Spark
Issue Type: New Feature
Components: ML, SQL
Affects Versions: 3.1.0
Reporter: Xiangrui Meng
More and more DS/ML workloads are dealing with tensors. For example, a decoded
color image can be represented by a 3D tensor. It would be nice to natively
support tensor type. A local tensor is essentially an array with shape info,
stored together. Native support is better than user-defined type (UDT) because
PyArrow does not support UDTs but it already supports tensors.
