Why Murr

Latency, simplicity, cost - pick two. Murr tries to nail all three.

vs Redis

Persistent. S3 is the new filesystem. Offloads cold data to local NVMe instead of burning RAM.

vs RocksDB

No need to build data sync yourself. Distributed from day one, stateless by design.

vs DynamoDB

Roughly 10x cheaper. You pay for CPU/RAM, not per query.

vs Postgres

Zero-copy wire protocol, no parsing overhead. Build np.ndarray or pd.DataFrame directly from the response.
