Abstract
Mechanisms are provided for managing caching of data in a multi-tenant cache storage device utilized by a distributed dataset based application. The mechanisms retrieve Resilient Distributed Dataset (RDD) block size information for an RDD associated with an application. A probability distribution of RDD block sizes is generated based on the RDD block size information and a maximum size for a RDD block of data is estimated based on the probability distribution. An amount of free space in a portion of the multi-tenant cache storage device allocated to the application is estimated based on the estimated maximum size for the RDD block of data. Cache operations for caching data associated with the application to the multi-tenant cache storage device are managed based on the estimated amount of free space in the portion of the multi-tenant cache storage device allocated to the application.
