Abstract
Techniques for using micro-journals to ensure crash consistency of a transactional application are provided. In one embodiment, a computer system can receive a transaction associated with the transactional application, where the transaction includes a plurality of modifications to data or metadata of the transactional application. The computer system can further select a free micro-journal from a pool of micro-journals, where the pool of micro-journals are stored in a byte-addressable persistent memory of the computer system, and where each micro-journal in the pool is configured to record journal entries for a single transaction at a time. The computer system can then write journal entries into the micro-journal corresponding to the plurality of modifications included in the transaction and commit the journal entries to the byte-addressable persistent memory.
