ToplingDB is a cloud native LSM Key-Value Store with searchable compression algo and distributed compaction

This is an implementation of RFC 6902 JSON Patch written in Java

Go library for protobuf compatible sstables, a skiplist, a recordio format and other database building blocks like a write-ahead log. Ships now with an embedded key-value store.

State-of-the-art nesting for 2D irregular strip packing

Pacman: An Efficient Compaction Approach for Log-Structured Key-Value Store on Persistent Memory

Optimize rocksdb compaction

EGEN - Externalizable implementation generator

Python wrapper of Sparrow, State-of-the-art Nesting for 2D irregular strip packing

Delta Lake Optimization Project: Hands‑on lab to explore partitioning, Z‑Ordering, compaction (manual & auto), Liquid Clustering, and VACUUM using a synthetic sales dataset in Databricks. Includes a step‑by‑step notebook to measure file scans, bytes read, and query performance for each optimization.

In this project, we demonstrate the fractal dimension (FD) and manual segmentation of the Magnetic Resonance Imaging (MRI) of the heart that quantify amount of trabeculae inside the heart.
