shahrah
A PostgreSQL proxy that keeps each user's data in their own region. Shards by a key you name, splits reads from writes, pools connections, and moves a key between regions while the application keeps reading and writing. No driver to install.

Could you build this?
No Building a PostgreSQL wire-protocol proxy that handles transparent dynamic sharding, live cross-region key migration without downtime, and connection pooling requires deep distributed systems and database engine expertise.
What it would actually take: The architecture requires a custom proxy server in Rust or Go parsing the PostgreSQL frontend/backend protocol directly, an internal SQL query analyzer to extract sharding keys and distinguish reads from writes, and an Raft/etcd-backed coordination metadata store. The hardest part is zero-downtime shard migration, which demands two-phase locking/write dual-buffering or logical replication CDC while routing in-flight transactions. This necessitates deep expertise in distributed database internals, SQL parsing, and network protocols.
