Loading data files into the in-memory database has become one of the bottlenecks affecting service continuity. Our demonstration showcases a hot-loading technique for in-memory databases: upon start-up, the system only creates the memory-mapped address space for the in-memory table space files, bypassing the traditional step of loading the entire data files from disk into memory. The database becomes ready for service within seconds while background threads continue to load the actual data pages in parallel.The demo will replay the complete hot-loading workflow and present a side-by-side comparison of startup latency and transaction throughput with and without hot-loading enabled.
