Abstract
This disclosure provides various techniques that may allow for key-level lock requests in a database to be managed by code that manages a memory buffer for the database. The transaction-level locks and other higher level locks may be managed by a separate lock manager. In an embodiment, the code inserts key-level lock requests in the record chain even if there is a conflict, and the key-level lock requests remain in the chain after the locks are subsequently granted. Preemption may also be supported in the record chain, in some embodiments.
