Abstract
Described are techniques for data processing and caching. In response to a client failing to retrieve contents of a data element from a cache location specified by a first data element identifier including a first content-based identifier, the contents of the data element are obtained and stored at a cache location specified by the first data element identifier. The contents of the data element are updated at a second point in time and stored as second contents in the data element source. The data element at the second point in time has a second content-based identifier. In response to the client failing to retrieve the second contents of the data element from a cache location specified by a second data element identifier including the second content-based identifier, the second contents of the data element are obtained and stored at a cache location specified by the second data element identifier.
