# SQLite3 Benchmark [![CircleCI](https://circleci.com/gh/ukontainer/sqlite-bench.svg?style=shield)](https://circleci.com/gh/ukontainer/sqlite-bench)
A SQLite3 benchmark tool.
Most of the code comes from [LevelDB](https://github.com/google/leveldb).
This is C version of [benchmarks/db_bench_sqlite3.cc](https://github.com/google/leveldb/blob/main/benchmarks/db_bench_sqlite3.cc).
## Building
SQLite3 is included in the repository.
```sh
$ make
```
## Usage
```
$ ./sqlite-bench --help
