Amazon RDS vs MonetDB

Amazon RDS has no write-up on Specifiction yet; its figures are above.

MonetDB is a free, self-hosted relational database system built primarily for analytics, data warehouses, and bulk processing such as business intelligence and scientific analysis. It provides a SQL-compliant interface with keys, joins, views, triggers, stored procedures, and ACID properties for concurrent transactions, though it is not tuned for high-volume transaction processing. Its columnar storage and parallel query execution target heavy analytical workloads. Tables are vertically fragmented into columns represented as Binary Association Tables, with persistent BATs implemented as memory-mapped files. SQL user-defined functions can aggregate, filter, operate over windows, or return tables. Prebuilt packages are available for 64-bit Linux and macOS, and 32-bit or 64-bit Windows. Native interfaces cover languages including Python, Java, Node.js, PHP, R, Go, and C# .NET, and a separate ODBC installer is available. Listed integrations include Tableau, SQLAlchemy, Django, and GeoTools. Client-server communication is unencrypted by default, though TLS can be used through a termination proxy. MonetDB was founded in 2004 and is based in Amsterdam.
