Aerospike 7 introduces multiple improvements to support high-speed data access and improve performance for real-time bidding and large-scale applications, with enhanced features such as secondary indexes on BLOBs, persistent key-ordered map indexes, and improved configuration options. The new features aim to simplify the development process and provide better performance, scalability, and efficiency for developers building complex applications that require predictable sub-millisecond access to billions or trillions of objects.
