C3 is a project initiated at CWI, to explore the compression benefits of exploiting column correlations. We introduce six new multi-column lightweight compression schemes that exploit different types of correlations between pairs of columns. We implemented a compression framework which uses both our multi-column compression schemes and conventional "single-column" compression schemes in combination. The addition of the multi-column schemes allows the framework to exploit any correlations it detects, and fall back to single-column schemes if none are detected for a column. The code base is forked from the BtrBlocks project from TU Munich.
