A transaction is identified in a transaction processing system. An identifier value is generated for the transaction based on a concatenation of a unique sequence value and an identifier offset value. The transaction is processed by using the identifier value as a database primary key in a database of the transaction processing system.

Database identifier generation in transaction processing systems

One or more processors initiate generation of an identifier based on the definitions of both a primary range and a secondary range. One or more processors obtain a unique sequence value from a unique sequence range of known maximum number of values. One or more processors determine an offset value based on, at least in part, the primary range and the secondary range. One or more processors add the offset value to the unique sequence value to generate an identifier value. Processing a transaction using the identifier value as a database primary key in a database of a transaction processing system.

Optimization of event aggregation in an event-driven system is provided. An event queue is queried for a current event. A workload affinity coefficient that describes the current event, at least in part, is read. A database is searched for one or more matching workload affinity coefficients. The current event and one or more events that are respectively associated with one or more matching workload affinity coefficients are aggregated, thereby generating an aggregated event.
