Data shaping to reduce memory wear in a multi-tenant database

A multi-tenant database may maintain a plurality of datasets on a memory device that is subject to degraded operation caused by a subset of possible state transitions within the device's memory cells. A storage engine may identify entropy characteristics of datasets, independently of other data...

Summary:A multi-tenant database may maintain a plurality of datasets on a memory device that is subject to degraded operation caused by a subset of possible state transitions within the device's memory cells. A storage engine may identify entropy characteristics of datasets, independently of other datasets hosted on the memory, and use the entropy to construct a symbol table that maps from data within the dataset to symbols that may be stored on the memory device with a minimized number of state transitions.
