BenchBase

Multi-DBMS SQL benchmarking framework via JDBC

BenchBase is a Multi-DBMS SQL Benchmarking Framework via JDBC, formerly known as OLTPBench. It's a multi-threaded load generator designed to produce variable rate, variable mixture load against any JDBC-enabled relational database with per-transaction latency and throughput logging.

Led modernization effort including migration from Ant to Maven, Java 21 upgrade, improved packaging with Calendar Versioning, SLF4J logging, extensive static analysis fixes, and refactored transaction handling. The framework supports 17+ industry-standard benchmarks including TPC-C, TPC-H, and YCSB.

Tech: Java, Maven, JDBC, Docker, PostgreSQL, MySQL, CockroachDB
