Abstract: The present subject matter relates to file system journaling. In one example upon occurrence of a journal flushing event, a journal working set size is compared with a dynamic journaling threshold. The journal working set size indicates size of aggregated journal entries stored in main memory of a computing system. Further, the aggregated journal entries include a new journal entry created in response to the journal flushing event. Further, the dynamic journaling threshold is based on size of unused space of the main memory. It is further determined whether aggregated journal entries stored in the main memory have to be flushed to a journal in a storage device of the computing system based at least on the comparing. The aggregated journal entries are flushed from the main memory to the journal in the storage device based on the determining.

Abstract: In one example, disclosed are techniques to update application data files between open and sync and/or between two consecutive syncs using a syncv operation, file descriptors associated with each modified application data file and associated transaction records in a transaction log file.
