Abstract

Can-follow concurrency control permits a transactionto read (write) an item write-locked (read-locked) by anothertransaction with almost no delays. By combining the merits of2PL and 2V2PL, this approach mitigates the lock contention notonly between update and read-only transactions, but also betweenupdate and update transactions.
