- server/src/utils/db.ts: export replicaDb client alongside primary prisma;
replicaDb uses DATABASE_REPLICA_URL when set, falls back to DATABASE_URL
so dev/staging environments work without a replica
- Route heavy read-only SELECT queries to the replica:
- adminAnalytics.ts (30-day transaction aggregation)
- adminTransactions.ts (up to 1000-row listing)
- adminSAR.ts (findMany/findUnique/count/groupBy) while keeping the
single sARReport.update() on the primary write path
- DATABASE_REPLICA_URL documented in .env.example with RDS and streaming
replication examples
- 4/4 read/write splitting unit tests pass
Closes Stellar-Fluid#234
