• Full transaction support
• High performance, efficiency, and safety
• Easy-to-use synchronous API (better concurrency than an asynchronous API... yes, you read that correctly)
• Support for user-defined functions, aggregates, virtual tables, and extensions
• 64-bit integers (invisible until you need them)
• Worker thread support (for large/slow queries)"
