Multi-thread commit log compression

    Details

      Description

      The initial commit log compression implementation can do about 240 megabytes/second (uncompressed input) on a fast (500 megabytes/sec) SSD.

      This is basically what I measured as the throughput of LZ4 against the same data.

      Assuming a 1.5x compression ratio that is 160 megabytes/second of output. Enough to saturate a spinning disk, but not an SSD.
