Abstract
A data storage system performs updating of a set of global counters stored in persistent storage accessible to a plurality of processing nodes of a data storage system, the global counters storing respective global count values describing associated units of data storage shared by the processing nodes for performing data storage operations. The updating includes, by each processing node, using a respective set of in-memory delta counters storing respective delta count values to track changes to respective global count values due to data storage operations performed by the processing node with respect to the units of data storage. A summarization process is regularly executed to merge the delta count values of the delta counters of all processing nodes into the respective global counters.
