Description

LadybugDB is a kuzu fork focused on becoming the defacto graph database at the heart of agent memory systems

LadybugDB: https://github.com/LadybugDB/ladybug/blob/main/README.md

Hackathon

My contributions were targeted towards overall improvement of ladybugDB

Arrow tables support

Significantly improved query processing on arrow tables by fixing arrow table scans. Arrow table support is very critical for efficient interop between different components in the graph processing pipeline like icebug, bugscope, etc as arrow offers zero-copy via C API

Icebug specification

Developed v1 icebug-format spec aiming at becoming the defacto standard for graph database. Also added ladybugDB's icebug implementation

Debian packaging

Maintainer of ladybugDB debian package. Packaged ladybugDB as a debian package and raised sponsorship request
