LMDB Credit in the CDX System
LMDB deserves explicit credit in the x64base story because it gives the CDX indexing lane a durable, high-performance embedded backend. The x64base design keeps two ideas separate:
- CDX is the logical container shown to users, students, and commands.
- LMDB is the physical backend used to store and traverse built index data.
That separation lets LabTalk teach database indexing at two levels. Beginners can learn records, logical order, tags, SET ORDER, and SEEK without needing backend vocabulary first. Advanced students can open the implementation layer and see how a memory-mapped key-value database can support ordered navigation, rebuild workflows, and index diagnostics.
See CDX and LMDB Indexing for the implementation-facing explanation.
