vertexdb
- 1. Vertex a graph database
- 2. disclaimer v0.1 make it work ~v0.5 <- we are here* v1.0 make it right v2.0 make it fast *in use at stylous.com
- 3. overview filesystem inspired small, simple, fast garbage collected
- 4. details HTTP protocol JSON data format transactions queues
- 5. data model nodes are collections of ordered key/value pairs a value can contain data or a pointer to another node keys for data begin with underscore
- 6. API mkdir, rm, size, link read, write, select queuePopTo, queueExpireTo transaction
- 7. sample requests /users/joe?action=mkdir /users/joe/zip?action=write& value=94114 /users?action=select& whereKey=zip& whereValue=94114
- 8. sample response [ {"name":"joe", "zip":"94114"}, {"name":"jill", "zip":"94114"} ]
- 9. implementation in C TokyoCabinet - storage libevent - async networking YAJL - json generation basic unit test coverage
- 10. how it works async i/o requests handled serially use small requests periodic backups & garbage collection
- 11. performance* OSX ~1,000s requests/sec Linux ~10,000s requests/sec? *not durable until periodic backup
- 12. multiple indexes? client code establishes conventions & maintains indexes path/all path/byDate path/byProductId
- 13. to-do list AUTH & SSL rewrite in Lua Lua as query & processing language replace TC with BDB or skipdb native FUSE support
- 14. would-like-to-do list distributed in-memory durable commits persistent connections
