CameoDB v0.3.7: Two-Phase Paging, Millisecond Recovery and a Windows Service
CameoDB v0.3.7 pages distributed searches in two phases for 5x faster warm queries, recovers from a crash in milliseconds and installs as a Windows service.
Topic
Architecture
The engine piece by piece: storage, search, transactions and the leaderless mesh.
CameoDB fuses an ACID key-value store and a full-text engine into one binary with a single write path. These posts follow that design from the storage layer up to a multi-node mesh. The Operate page covers running it, and the query syntax shows what the search engine accepts.
