A plurality of transactions are handled in a database. Each transaction comprises a plurality of operations on at least one record in the database with at least two of the transactions being handled concurrently. Thereafter, a temporary timestamp is assigned to each record that is based, at least in part, on the corresponding transaction. A first transaction among the plurality of transactions is subsequently committed. Afterwards, re-stamping of at least one commit timestamp modified by the first transaction is delegated. Related apparatus, systems, techniques and articles are also described.
