Retrofitting a Foundation for CouchDB
Talkat FoundationDB Summit 2019 · on Monday, 2019-11-18· at 09:20· Grand Ballroom 5, Marriott Marquis San Diego Marina·
summary
CouchDB is being refactored to run on FoundationDB: bindings exist, core persistence moves under CouchDB 4.0, and a working prototype implements documents, indexes, change feeds and replication. The retrofit eliminates edit conflicts for single-region deployments, uses versionstamp-based change feed keys and metadata-version caching to avoid hot reads, and runs with a three data‑hall deployment model. Many features are v1 and functional; performance and operational hardening remain work in progress.
