Antoine Pitrou updated ARROW-11335:
-----------------------------------
Priority: Major (was: Minor)
> [C++] Support FixedSizeList JSON parsing
> ----------------------------------------
>
> Key: ARROW-11335
> URL: https://issues.apache.org/jira/browse/ARROW-11335
> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++
> Reporter: Johan Peltenburg
> Priority: Major
> Labels: good-first-issue
>
> Currently, the C++ JSON table reader does not support the Arrow FixedSizeList
> type.
> When the Arrow schema is not inferred but supplied to the parser, it should
> attempt to turn JSON arrays into an Arrow FixedSizeList if the schema
> dictates this for specific fields.
> This currently results in the JSON table reader returning an error, e.g.:
> {code:java}
> JSON conversion to fixed_size_list<item: uint64 not null>[12] is not
> supported{code}
