> It would be interesting to see the performance of lzo compressed Column Families Vs Normal ZlibBlock Compression. Based on some very preliminary performance profiling that I have done, as long as the cells are of reasonable size ( > 4k ), the zlib compression really dominates the overhead in random read/scanning situations.
