The pyarrow DictionaryArray class has a `dictionary_decode()` method, as a counterpart of the `dictionary_encode()`. However, this is not an actual kernel, but just implemented manually (it's also just a simple "take" of course): https://github.com/apache/arrow/blob/fe88d9ad5c346786842913c8d2a369db099b5406/python/pyarrow/array.pxi#L2506-L2510 It would be nice to make an actual kernel for this, just like we have a "dictionary_encode" kernel (and eg also "run_end_encode" and "run_end_decode" kernels). Among other things, this makes it available as a function in pyarrow.compute (and for example ensures you can call this on a chunked array more easily). -- This is an automated message from the Apache Git Service.
