Patent attributes
A computer-implemented method, a computer-readable medium and a system are provided. A transaction master for each of a plurality of transactions of a database is provided. Each transaction master is configured to communicate with at least one transaction slave to manage execution of a transaction in the plurality of transactions. Each transaction master configured to perform generating a transaction token to specify data to be visible for a transaction on the database, the transaction token including a transaction identifier for identifying whether the transaction is a committed transaction or an uncommitted transaction, receiving a request to commit the transaction, initiating, based on the request, a two-phase commit operation to commit the transaction. The two-phase commit operation includes preparing for committing the transaction, writing a committed transaction to a memory, optimizing the two-phase commit operation by omitting a phase of the two-phase commit operation, generating an acknowledgement of the committed transaction. The plurality of transactions of the database are executed with each transaction master.
