The Julia implementation (Arrow.jl) has the ability to output an
Arrow.Table as a JSON array of objects or object of arrays via the
JSONTables.jl package, like:
using Arrow, JSONTables
julia> t = Arrow.Table("tbl.arrow")
Arrow.Table with 4 rows, 1 columns, and schema:
:a String
julia> arraytable(t)
"[{\"a\":null},{\"a\":\"a\"},{\"a\":\"b\"},{\"a\":\"a\"}]"
julia> objecttable(t)
"{\"a\":[null,\"a\",\"b\",\"a\"]}"
You can also provide an IO argument as the 1st argument to
arraytable/objecttable to write the results out to a file directly.
In case that helps at all!
