Abstract
Techniques for updating persistent statistics on a multi-transactional and multi-node storage system. The techniques can be practiced in a distributed storage system including a plurality of storage nodes. Each storage node can include a persistent storage configured to accommodate a set of delta counter pages, as well as a global counter page for summarizing delta count values tracked by respective delta counters. The techniques can include, in each storage node, tracking, by each of a set of delta counters, changes to delta count values due to storage node operations performed on units of data storage, and summarizing, periodically or at least at intervals, the delta count values of the respective delta counters as global count values. The techniques can further include summarizing the global count values across the respective storage nodes in a count summarization report and sending the count summarization report to a client via a communications interface.
