Value-cognizant Speculative Concurrency Control
Summary: Proposes SCC-kS, a speculative concurrency control that allows up to k shadow transactions per uncommitted txn to reduce blockages and boost timely commits. Introduces SCC-DC, a value-cognizant variant that leverages deadlines and criticalness to defer commits for timeliness; simulations show gains over standard CC in real-time databases.
