> As we know, roaring bitmap will compress its contents. There's no need to use
> {{CompressionUtils.compress}} to compress again the results of each region,
> which is time consuming and whose compression ratio is low. One example is as
> follows:
> Etc message: start latency: 39@1,agg
> done@{color:#f79232}1094{color},cpuTime@1090,compress
> done@{color:#f79232}4245{color},server stats done@4246
> endpoint.CubeVisitService: Size of final
> result = {color:#f79232}61,157,510{color} ({color:#f79232}64,725,324{color}
> before compressing)
