Abstract
A decentralized two-phase commit in a datastore or database includes determining pre-validating a transaction, writing first metadata to a leader partition, the first metadata including a state indicating preparing and mutations of the transaction, and writing second metadata of a follower partition to indicate the follower partition is locked by the leader partition. The decentralized two-phase commit further includes updating the state of the first metadata to indicate committed and performing the transaction on the leader partition, performing the transaction on the follower partition and unlocking the follower partition, and updating the first metadata to remove the mutations of the transaction and updating the state of the first metadata to indicate the transaction is completed. The decentralized two-phase commit may further include selecting a leader partition key and updating the state of the first metadata to indicate committed unapplied.
