Abstract

A database operation is initiated in an in-memory database that stores persistent data in a secondary storage and has at least one associated log. The database operation involves data having a size above a pre-defined threshold. Thereafter, the data is split into a plurality of chunks and the database operation is executed by parallelizing each chunk over a plurality of hierarchically arranged threads. Related systems, apparatus, methods and computer program products are also described.
