Abstract
A searchable metadata change log is maintained in a persistent memory of a data storage system, and stores metadata changes to be aggregated and applied to data storage system metadata located in non-volatile data storage. New metadata changes are added to the metadata change log by storing the new metadata changes into the persistent memory, storing structural modifications to the metadata change log needed to add the new metadata changes to the metadata change log into a transaction entry located in the persistent memory, and processing the resulting transaction entry to perform the structural modifications to the metadata change log that were stored in the transaction entry.
