LGTM - thanks for the patch @janniklinde. No changes were needed during the merge, and I like the approach of simultaneously pulling from both input streams which can exploit co-sorted streams. |

This patch adds a new out-of-core centralMoment instruction. If a weight matrix is provided, a simple hash-join aligns the matrix blocks (without eviction or back-pressure strategies). Weight matrix support is limited to aligned blocks with matching block-sizes.
