Cool! I will open a "roadmap" issue shortly...it should exist somewhere. I think what you are after might be a good fit for the C library ( see https://apache.github.io/arrow-nanoarrow/dev/c.html#creating-arrays ), which would let you construct a RecordBatch with perhaps less indirection. Your example might be something like: ```c struct ArrowSchema schema; ArrowSchemaInit(&schema, NANOARROW_TYPE_STRUCT); ArrowSchemaAllocateChildren(&schema, ncol); struct ArrowArrray array; ArrowArrayInit(&array, NANOARROW_TYPE_STRUCT); ArrowArrayAllocateChildren(&array, ncol); array.length = rows; array.null_count = -1; for (size_t i=0; i<ncol; i++) { // ...fill in schema.children and array.children } ``` That said, as long as the external pointers carry the class `"nanoarrow_schema"`, `"nanoarrow_array"` and `"nanoarrow_array_stream"` I think an "arch" package that provides that type of C API would happily augment anything that exists in nanoarrow. I don't envision providing access to C callables in the initial release, mostly because my development focus will be on more user-facing behaviour (like ALTREP conversions). -- This is an automated message from the Apache Git Service.
