Different I/O Access Methods for Linux - ScyllaDB's Choice and Rationale

Explore the intricacies of I/O access methods for Linux in this 57-minute webinar sponsored by ScyllaDB. Gain a comprehensive understanding of four file access options on Linux servers: read/write, mmap, Direct I/O (DIO) read/write, and asynchronous direct I/O (AIO/DIO). Examine the tradeoffs between these methods, focusing on key aspects such as cache control, copying, MMU activity, and I/O scheduling. Discover why ScyllaDB opted for AIO/DIO in their high-performance, low-latency database design, and learn about the long-term impact of this decision on their engineering efforts and product performance over the past seven years. Ideal for server application developers and database engineers seeking to optimize I/O operations and enhance system performance.
