Abstract
A computer-implemented method, a computer program product, 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 a transaction in the plurality of transactions. A transaction token that specifies data to be visible for the transaction on the database is generated. The transaction token includes a transaction identifier for identifying whether the transaction is a committed transaction or an uncommitted transaction. The transaction master is configured to update the transaction token after execution of the transaction. A determination whether the transaction can be executed on the at least one transaction slave without accessing data specified by the transaction token is made. The transaction is executed on the at least one transaction slave using a transaction token stored at the at least one transaction slave.
