Abstract
Described are techniques for processing data operations. A read request for first data is received at a data storage system. It is determined whether the read request results in a cache hit whereby the first data is stored in a cache of the data storage system, or whether the read request otherwise results in a cache miss. If the read request results in a cache miss, processing is performed to determine determining whether to perform cacheless read processing or deferred caching processing to service the read request. Determining whether to perform cacheless read processing or deferred caching processing is performed in accordance with criteria including a measurement indicating a level of busyness of a back-end component used to retrieve from physical storage any portion of the first data not currently stored in the cache.
