SeaweedFS is a distributed file system with optimization for small files. It can also be used as a key-value store for large values.

Download the YCSB from this website:

https://github.com/brianfrankcooper/YCSB/releases/

You can choose to download either the full stable version or just one of the available binding.

To execute the benchmark using the SeaweedFS storage binding, first files must be uploaded using the "load" option with this command:

   ./bin/ycsb load seaweedfs -p seaweed.filerHost=localhost -p seaweed.filerPort=8888 -p seaweed.folder=/ycsb -p fieldlength=10 -p fieldcount=20 -p recordcount=10000 -P workloads/workloada

With this command, the workload A will be executing with the loading phase. The file size is determined by the number of fields (fieldcount) and by the field size (fieldlength). In this case each file is 200 bytes (10 bytes for each field multiplied by 20 fields).

Running the command:

   ./bin/ycsb run seaweedfs -p seaweed.filerHost=localhost -p seaweed.filerPort=8888 -p seaweed.folder=/ycsb -p fieldlength=10 -p fieldcount=20 -p recordcount=10000 -P workloads/workloada

the workload A will be executed with file size 200 bytes.
