Hi guys, I'm writing an cross-language row-oriented serialization framework mainly for java/python for now. I detained many data types and schema, field, such as Byte, short, int, long, double, float, map, array, struct,. But then I find using Arrow schema is a better choice. Since my framework need to support conversion between my row-format and arrow columnar format. If I do all it by myself, I need to support schema conversion and schema serialization. Which is not necessary if I use arrow schema.
But I find that arrow doesn't have a map data type, which is I needed exactly. I know I can use struct to mock it or ExtensionType for it. But it's not very convenient. So I want to know whether will Map type be supported by arrow? Thanks. Regards
