Hi Suhail, I'm not sure there are any convenience function to initialize an ArrayBuilder class from an existing Array. But I imagine you should be able to use the cython definitions in "python//pyarrow/includes/libarrow.pxd" and use it in the way you describe. It might help if you can provide a pointer to minimal code sample.
