H2CO3 opened a new issue, #7414: URL: https://github.com/apache/arrow-rs/issues/7414
**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** I'm trying to use LanceDB through FFI. I am transfering the initial data as serialized JSON across the FFI boundary. I am trying to deserialize the JSON according to a schema then insert it into a table. Unfortunately, when I specify in the schema that one of the fields should be a `FixedSizeList`, and specify identically-sized arrays for that field in my JSON, I get an error saying that it is not yet supported. I see that `List` and `LargeList` are already supported; can you please implement `FixedSizeList` too? **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> `arrow_json::Reader` should not choke on `FixedSizeList`-typed fields. Instead, the deserializer should verify that the corresponding JSON value is an array of the expected length, and correctly deserialize it from the data. **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
