Krisztian Szucs updated ARROW-9999:
-----------------------------------
Description:
{code:python}
pa.array(["some", "string"], type=pa.dictionary(pa.int8(), pa.string)))
{code}
raises
{code}
ArrowNotImplementedError: Sequence converter for type dictionary<values=string,
indices=int8, ordered=0> not implemented
{code}
It would be a much more comfortable way than
{code:python}
pa.DictionaryArray.from_arrays(indices, dictionary)
{code}
And possibly more efficient as well thanks to the adaptive dictionary builders.
