- Introduce RoutingPrismaWrapper that transparently routes read operations (find_*, count, group_by, query_raw, query_first) to a reader endpoint while writes remain on the writer, enabling Aurora-style reader/writer endpoint splits - Add IAMEndpoint dataclass and parse_iam_endpoint_from_url() to capture static connection fields from a reader URL so only the IAM token needs to rotate, avoiding the need for separate DATABASE_HOST_READ_REPLICA/etc. env vars - Enhance PrismaWrapper with per-instance knobs (db_url_env_var, iam_endpoint, recreate_uses_datasource, log_prefix) so writer and reader wrappers are independent: the reader writes its fresh URL to DATABASE_URL_READ_REPLICA and passes datasource override to Prisma since Prisma only auto-reads DATABASE_URL - Fix deadlock in PrismaWrapper.__getattr__: when called from inside a running event loop, schedule the token refresh as a background task instead of blocking with run_coroutine_threadsafe + future.result(), which would deadlock the loop thread waiting for a coroutine that needs the loop to run - Fix botocore crash when DATABASE_PORT is unset by defaulting to "5432" in both proxy_cli.py and PrismaWrapper.get_rds_iam_token(); passing None caused botocore to embed the literal string "None" in the presigned URL - Implement graceful reader degradation: reader connect/recreate failures are non-fatal; wrapper sets _reader_unavailable=True and silently routes reads to the writer to keep the proxy serving traffic during transient reader outages - Add PrismaClient.writer_db property so the reconnect smoke-test always validates the writer engine specifically; query_raw on the routing wrapper would route to the reader and not verify the newly-recreated writer - Expose DATABASE_URL_READ_REPLICA in Helm chart (values.yaml + deployment.yaml) via both plain value and secret key reference, and document the field in docker-compose.yml - Add 887-line test suite covering routing logic, IAM token refresh paths, reader degradation scenarios, datasource override behavior, and the deadlock regression Co-authored-by: Yassin Kortam <yassinkortam@g.ucla.edu>
