----------------------------------
I compare the performance of cross space copmaction and unseq inner space
compaction for aligned timeseries among three commits.
b309f71b959044cda2c5c37ca96bf89c69fbd640: {*}{*}Row-based data block +
row-based data process
70772cb8684315814959974811440f746e5c19c3: Column-based data block + row-based
data process
def138b5909e5df76440836719b62ebc4b48daeb: Column-based data block +
column-based data process
21 sequence tsfile and 21 unsequence tsfiles with one storage group, 100
devices, 300 sensors, and average 235470 points on each sensor.
unsequence inner space copmaction:
b3: 3.4932 Mb/s
70: 2.3602Mb/s
de: 4.4297Mb/s
cross space compaction:
b3: 1.9377 Mb/s
70: 2.1735Mb/s
de: 2.7183Mb/s
> Improve the process of writing chunks in compaction for aligned series
