Abstract
A plurality of transactions in a data storage application are executed during which log entries according to the plurality of transactions are stored in a plurality of log buffers. The log entries are sequentially written into a current log buffer and the plurality of log buffers are written to a plurality of log partitions according to a round-robin distribution. Thereafter, in response to a data recovery event, a sequential list of the log entries in the log buffers are assembled to generate a log that can be used for data recovery by the data storage application. Related apparatus, systems, techniques and articles are also described.
