Dec 1, 2024December 2024: Delivered a read replica database for unicef/hope to improve read performance and scalability. Configured environment variables and settings to direct read-only operations to the replica; this reduces load on the primary database and enhances query latency for read-heavy workloads. Implemented a minor GraphQL schema change to rename a payment verification field to reflect updated payment verification flow. All changes were committed under c3adb142d83cfa222dcc538d3d9f4ffc42081282 with message 'change to use replica db (#4530)'.
