  11. def compress(tableId: Int, contigTable: ContiguousTable, stream: Stream): CompressedTable

    Compress a contiguous table.

    Compress a contiguous table.

    The compressed buffer MAY NOT be ideally sized to the compressed data. It may be significantly larger than the size of the compressed data. Releasing this unused memory will require making a copy of the data to a buffer of the appropriate size.
