Comparing nested types for equality to run-end encode them can be expensive and unlikely to bring good compression rates. Run-end encoding works better on flat columns. That said, the most likely reason for a kernel not supporting REE arrays yet is usually: it hasn't been implemented. Because, you know, it takes time ($) to implement custom kernels for REE arrays. -- This is an automated message from the Apache Git Service.
