Conference talks and seminars on DBMS internals, 3D GIS, and the systems-software layer in between.
Hyung-Gyu Ryoo
Research engineer at CUBRID. I read storage engines line by line and write down what I find — concurrency control, MVCC, recovery, and the systems-software layer around them.
Notes & Analyses
Long-form code analyses on CUBRID’s storage engine — lock manager, MVCC, recovery, page buffer, and the rest.
Open-source
3D extensions for GeoServer / GeoTools, SFCGAL4J, IndoorGML tooling, and other things that ended up on GitHub.
