Amazon Aurora vs LevelDB

Amazon Aurora is a MySQL and PostgreSQL-compatible relational database service built for the cloud, offered as part of Amazon Web Services. It provides up to five times the throughput of standard MySQL and three times that of PostgreSQL with automatic scaling, replication, and backup.

LevelDB is fast embedded key-value storage library from Google with ordered mapping from string keys to string values. It provides comprehensive features for databases workflows. The tool is actively maintained with regular updates and strong community/vendor support.
