Amazon RDS vs KeyDB

Amazon Relational Database Service (RDS) is a managed database service from AWS that supports MySQL, PostgreSQL, MariaDB, Oracle, SQL Server, and Db2 engines. It automates hardware provisioning, database setup, patching, and backups with options for Multi-AZ deployments and read replicas.

KeyDB is multithreaded fork of Redis offering higher throughput on multi-core hardware while maintaining protocol compatibility. It provides comprehensive features for databases workflows. The tool is actively maintained with regular updates and strong community/vendor support.
