Abstract
Techniques for handling mixed metadata (MD) updates using an MD delta log and log structured MD. The techniques include, while performing a transaction commit operation, writing, to an MD delta log, raw delta updates to MD pages, logical-to-physical address translation table (TT) updates for MD pages containing bulk updates, and specialized flags for the MD pages containing bulk updates. For each MD page containing bulk updates, raw delta updates, a TT update, and a specialized flag are written to the MD delta log in association with a transaction identifier. The techniques include generating an MD stream for the MD pages containing bulk updates, and passing the MD stream to an MD pages tier of a storage array. The techniques include, in response to a predetermined event, replaying the MD delta log to apply valid delta updates to at least one MD page containing bulk updates in the MD pages tier.
