Abstract:
Replay of data transactions is initiated in a data storage application. Pages of a log segment directory characterizing metadata for a plurality of log segment are loaded into memory. Thereafter, redundant pages within the log segment directory are removed. It is then determined, based on the log segment directory, which log segments need to be accessed. These log segments are accessed to execute the log replay. Related apparatus, systems, techniques and articles are also described.
