Methods and systems for distributed caching in presence of updates and in accordance with holding times

   
   

Techniques for improved cache management including cache replacement are provided. In one aspect, a distributed caching technique of the invention comprises the use of a central cache and one or more local caches. The central cache communicates with the one or more local caches and coordinates updates to the local caches, including cache replacement. The invention also provides techniques for adaptively determining holding times associated with data storage applications such as those involving caches.

As técnicas para a gerência melhorada do esconderijo including a recolocação do esconderijo são fornecidas. Em um aspecto, uma técnica caching distribuída da invenção compreende o uso de um esconderijo e um um ou mais central esconderijos locais. O esconderijo central comunica-se com o um ou mais esconderijo do local e coordena-se updates aos esconderijos locais, including a recolocação do esconderijo. A invenção fornece também técnicas para adaptàvel determinar mantendo épocas associadas com as aplicações do armazenamento de dados de tais como aqueles que envolvem esconderijos.
