Concurrent transaction processing in a database system

A method comprising:

• receiving a first transaction, the first transaction to be executed on linearizable storage;
• assigning a first read version to the first transaction, the first read version indicating a first version of the linearizable storage;
• performing a read operation from the first transaction on a table in a database;
• determining a first commit version identifier corresponding to first data resulting from the read operation;
• and
• in response to determining that a particular write operation is absent from the first transaction, proceeding to execute a different transaction and foregoing to perform a commit process in connection with the first transaction.

A computer-storage medium comprising instructions that, when executed by one or more processors of a machine, configure the machine to perform operations comprising:

• receiving a first transaction, the first transaction to be executed on linearizable storage;
• assigning a first read version to the first transaction, the first read version indicating a first version of the linearizable storage;
• performing a read operation from the first transaction on a table in a database;
• determining a first commit version identifier corresponding to first data resulting from the read operation;
• and
• in response to determining that a particular write operation is absent from the first transaction, proceeding to execute a different transaction and foregoing to perform a commit process in connection with the first transaction.
