Abstract
Processing is provided for operating an in-memory database, wherein transaction data is stored by a persistence buffer in an FIFO queue, and update processor subsequently: waits for a trigger; extracts the last transactional data associated with a single transaction of the in-memory database from the FIFO memory queue; determines if the transaction data includes updates to data fields in the in-memory database which were already processed; and if not, then stores the extracted transaction data to a store queue, remembering the fields updated in the in-memory database, or otherwise updates the store queue with the extracted transaction data. The process continues until the extracting is complete, and the content of the store queue is periodically written into a persistent storage device.
