Abstract
A database system with a transactional commit protocol based on a safe conjunction of majorities is disclosed. In various embodiments, a directed acyclic graph comprises, for each of a plurality of transactions, data identifying the transaction, data indicating prior transaction(s) on which the transaction depends, and data indicating whether the transaction has been committed. A processor associated with a resource manager of a first database server included in a plurality of database servers each having a resource manager, determines a leading edge comprising a set of committed leaf nodes of the directed acyclic graph. The processor provides data representing a respective leading edge from each respective resource manager, and determines to commit a transaction based on a determination that a majority of the resource managers have indicated they agree on a consistent starting state and ending state for the transaction.
