June 2025 performance summary for apache/couchdb: The primary focus was migrating the Nouveau component's HTTP client from HTTP/1.1 (ibrowse) to HTTP/2 (gun). This reduces the number of concurrent connections between CouchDB and the Nouveau server, potentially improving throughput and lowering resource usage. The migration introduces a trade-off: loss of HTTP/1.1 pipelining benefits for indexing. The work advances the architecture toward modern HTTP protocols and sets the stage for future performance optimizations with minimal user-facing impact.
