LedgerBench

Overview

This repository implements LedgerBench, a benchmark framework for ledger databases outlined in IEEE Data Engineering Bulletin paper (June 2022). LedgerBench evaluates all main components of a ledger database, namely ledger storage, query processing, verification, and auditing. It provides comprehensive performance analysis with verification-aware micro- and macro-benchmarks. Meanwhile, LedgerBench provides user friendly extensible APIs. Users can easily add their customized workloads and new ledger databases for benchmarking.

Code structure

/workload - Contains workload interface and implementations. The implementation of workload is placed under specific folder and implementing common APIs specified in workload.h. In this repository, we provide default implementation for YCSB, SmallBank, and TPCC.
/analyzer - Provides scripts to process the log generated during workload execution.
/dbadapter - Contains DB adapter interface and implementations. Users can add new adapter for the database to be evaluated by implementing a list of common database APIs defined in dbadapter.h. Users shall put their implementation files in a separate folder, and provide start_server.sh and stop_server.sh in the conf folder.
/dbs - (Optional) Contains executables and shared libraries of the database under evaluation. The database can be installed anywhere else with the db_bin_dir specidified in the conf.sh
- ledgerdb - We provide with an example that is built from LedgerDatabase.
```
$ gitclone https://github.com/nusdbsystem/LedgerDatabase
$ cd LedgerDatabase
$ mkdir build && cd build
$ cmake -DCMAKE_INSTALL_PREFIX=<ledgerbench_root_dir>/dbs/ledgerdb .. && make
$ make install
```
/exps - Contains the program and scripts to start the experiments.
- conf.sh - The configurations and environment to run the experiments.
- run_exps.sh - Script to start the experiments
