Twisted Twin: A Collaborative and Competitive Memory Management Approach in HTAP Systems
Summary: T2 (Twisted Twin) is an adaptive memory management scheme for co-located OLTP/OLAP in HTAP that jointly reasons about memory allocation, in-memory column selection, and synchronization effects to avoid SLA violations while improving OLAP efficiency. Uses a Bayesian optimization loop tuned for fluctuating workloads to dynamically balance collaborative sharing and competitive isolation; implemented in GaussDB-HTAP and shown to improve OLTP SLA compliance and OLAP throughput.
