Our program can get the minimal write amplification of RocksDB of a given workload.

e.g. ./run_all.sh 1000000 0 0 ./tmp 800 here is the explanation to the parameter

1. the number of inserted in the workload
2. the number of updates in the workload
3. the number of deletes in the workload
4. the path to save the experiments result
5. the number of times to run kEnumerate

After completing running, you can find there is a folder whose name is the pattern of the workload. In this folder, there are four things. Folder "history" records the picking history. Folder "result" records the write amplification of each run and the minimum write amplification so far. The write amplification of KRoundRobin and KMinOverlappingRatio are recorded in the first two lines in result.txt. Besides, the workload and logs are also included.

This repo doesn't contain the files needed to compile RocksDB, if you want to get the library of RocksDB to this project, please refer to https://github.com/weirande2009/cs561-research-project where we modify the source code of RocksDB.
