Automated TPC-DS and TPC-H benchmark for Apache Hive LLAP

A repo containing parallel, high-performance TPC-H data generation utilities

TPC-H benchmark test tool with result analysis feature and multi-DB support

Apple Silicon Unified Memory for GPU-Accelerated Analytics — TPC-H benchmarks across DuckDB, NumPy, and MLX

The Query Visualiser takes in a query as an input and outputs the most efficient query execution plan

Assignments for the Computer Systems Performance course at the IT University of Copenhagen

An CS465 - Advanced Database project comparing custom query engine performance against DuckDB across TPC-H-like datasets with benchmark scripts, engines, and results.

ETL (Extract, Transform, Load) pipeline for converting an OLTP relational schema into an OLAP star schema using Apache NiFi, MySQL, and Apache Spark.

Reproducible single-host benchmark suite (TPC-H, TPC-DS, SSB, JOB) comparing DeltaForge, DuckDB, and Apache Spark on identical Delta tables. Apache 2.0.

This project compares five lossless data compression techniques—Binary, Run-Length, Dictionary, Frame of Reference, and Differential Encoding—applied to integer and string CSV data. The performance is evaluated in terms of compression ratio, file size, and encoding/decoding time

TPC-H

A Docker-based microservices project converts natural language questions to SQL queries using local LLMs.

SQL Query Benchmarks Archive, Queries, Schemas, and Dockerfiles

Rule-based SQL query optimizer in Python (sqlglot) featuring composable AST rewrites: predicate pushdown, projection pruning, and constant folding. Paired with a React visualizer rendering logical plans as annotated node graphs with per-pass telemetry.

An implementation of the TPC-H benchmark for Postgres.
