Hi,

Was wondering if it would be possible to add to_arrow support on AccumulatedCSR [link] in addition to SciPy?

def to_arrow(self):
        return pa.SparseCSRMatrix.from_numpy(data=self.data, indptr=self.indptr, indices=self.indices, shape=self.shape)

Or is there another way to get a PyArrow CSR object from SOMA?
