Massively Parallel Multi-Versioned Transaction Processing
Offered By: USENIX via YouTube
Course Description
Overview
Explore a 15-minute conference talk from USENIX's OSDI '24 program that introduces Epic, the first multi-versioned GPU-based deterministic OLTP database. Delve into how Epic leverages a batched execution scheme to perform concurrency control initialization for multiple transactions before deterministic execution. Discover how this approach eliminates version search, reduces version allocation and garbage collection overheads, and utilizes GPU architecture to accelerate concurrency control initialization and parallelize transaction execution. Learn about Epic's performance advantages, particularly under medium to high contention scenarios, compared to state-of-the-art single and multi-versioned systems. Gain insights into the innovative solutions addressing the complexity and overhead challenges typically associated with multi-versioned systems in OLTP workloads.
