This is a YCSB workload generator. It is modified from project YCSB-C.
We strip functionalities other than generating dataset and query workload from default key space. Besides, we add support for user-defined key space, which is very helpful in testing dataset-sensitive indices or key value stores.
-
To build YCSB-Gen on ubuntu, for example:
mkdir build cd build & make
-
To generate a dataset and workload file from default key space.
./ycsbc -P workloads/workloada.spec
This command will generate two files,
dataset.datandquery.dat. Thedataset.datcontains insert queries to load initial data against your DB, and the latter contains workloads to benchmark your DB. -
To generate a dataset and workload file from given key space. You should provide a key set file that contains sufficient lines of keys that you want to draw from.
./ycsbc -P workloads/workloada.spec -F <your keyset file>
