-----------------------------------
According to [experiment
results|https://cwiki.apache.org/confluence/display/IOTDB/Experiments+of+TsFile+index+area#ExperimentsofTsFileindexarea-(II)ExperimentaboutcombineChunkandPage]:
There are about 7,977 data points in one 64K chunk;
There are about 125,000 data points in one 1M chunk;
There are about 260,000 data points in one 2M chunk;
There are about 390,000 data points in one 3M chunk;
There are about 520,000 data points in one 4M chunk.
Discuss the scenarios below: (only one timeseries)
1. For a scenario that generates 5 data points per second. (one chunk one day)
(5Hz frequency)
One day will generate 432,000 points (about 54 pages). Therefore, 1 chunk has
54 pages (about 3.4M).
2. For a scenario that generates one data point per second. (one chunk one day)
(1Hz frequency)
One day will generate 86,400 points (about 11 pages). Therefore, 1 chunk has 11
pages (about 693K).
3. For a scenario that generates 5 data points per minute. (one chunk one day)
(1/12Hz frequency)
One day will generate 7200 points (about 1 pages). Therefore, 1 chunk has 1
page (about 56.6K).
4. For a scenario that generates one data point per minute. (one chunk one
week) (1/60Hz frequency)
One week will generate 10080 points (about 1.3 pages). Therefore, 1 chunk has
1~2 pages (about 79.3K).
