URL: https://github.com/apache/iotdb/pull/14693#issuecomment-2587028660
## File Structure
+ `iotdb/`: include the scripts and database used for evaluations
+ `OrderSensitiveTimeEncoder&OrderSensitiveValueEncoder`: the encoding
method proposed in the paper
+ `CompressedBubbleSorter`: the compressed bubble sort algorithm
proposed in the paper
+ `CompressedMergeSorter`: the compressed merge sort algorithm proposed
in the paper
+ `datasets/`: include all the public datasets used for evaluations
## Steps
+ `Compresseion performance`: all the test code for encoder performance is
in `EncodeDecodeTest.java`
+ `Compressed bubble sort performance`: all the test code for Memtable sort
performance is in `CompressedBubbleSorterTest.java`
+ `prepareData()`: choose the dataset that will be used in the following
test
+ `testSortTime()`: for the specified parameters, test the sort time of
different methods.
+ `testCompressedBubbleSortMemory() & testOldSortMemory()`: for the
specified parameters, test the heap usage for compressed bubble sort and other
methods
+ `Compressed merge sort performance`: all the test code for Compaction sort
performance is in `CompressedMergeSorterTest.java`
+ `prepareData()`: choose the dataset that will be used in the following
test
+ `testMergeTime()`: for the specified parameters, test the merge time
of different methods
+ `testNewMemoryPrepare() & testOldMemoryPrepare()`: for the specified
parameters, prepare the compressed data that will be used in the following test
+ `testNewMemory() & testOldMemory()`: for the specified parameters,
test the heap usage for compressed merge sort and other methods.
