Abstract
Techniques for implementing metadata streams that provide increased performance and resiliency. The techniques include writing raw delta updates of metadata pages to a metadata delta log, and generating a metadata stream for a metadata page containing bulk updates. The techniques include passing the metadata stream to a tiered storage array, and storing the metadata page in a physical block on a metadata page tier. The techniques include, in response to storing the metadata page in the physical block, updating, in local memory, parity data for a RAID stripe including the metadata page. The techniques include, once the physical block is filled with metadata pages, storing the parity data from the local memory to a parity page of the stripe. The techniques include, in response to a storage drive failure when the physical block is partially filled with metadata pages, rebuilding the stripe data using the parity data in local memory.
