Abstract: The subject disclosure is directed towards a multi-tiered cache having cache tiers with different access properties. Objects are written to a selected a tier of the cache based upon object-related properties and/or cache-related properties. In one aspect, objects are stored in an active log among a plurality of logs. The active log is sealed upon reaching a target size, with a new active log opened. Garbage collecting is performed on a sealed log, such as the sealed log with the most garbage therein.
