Abstract: "Long lived transactions (LLTs) hold on to database resources for relatively long periods of time, significantly delaying the completion of shorter and more common transactions. To alleviate this problems [sic] we propose an extension to two-phase locking, called altruistic locking, whereby LLTs can release their locks early.

Abstract: "Long lived transactions (LLTs) hold on to database resources for relatively long periods of time, significantly delaying the completion of shorter and more common transactions. To alleviate this problems [sic] we propose an extension to two-phase locking, called altruistic locking, whereby LLTs can release their locks early. Transactions that access this released data are said to run in the wake of the LLT and must follow special locking rules. Altruistic locking guarantees serializability and does not a priori specify an order in which database objects must be accessed."
