Abstract: Cache optimization. Cache access rates for tenants sharing the same cache are monitored to determine an expected cache usage. Factors related to cache efficiency or performance dictate occupancy constraints. A request to increase cache space allocated to a first tenant is received. If there is a second cache tenant for which reducing its cache size by the requested amount will not violate the occupancy constraints for the second cache tenant, its cache is decreased by the requested amount and allocated to satisfy the request. Otherwise, the first cache size is increased by allocating the amount of data storage space to the first cache tenant without deallocating the same amount of data storage space allocated to another cache tenant from among the plurality of cache tenants.

Abstract: Systems and methods for cache optimization are provided. The method comprises monitoring cache access rate for a plurality of cache tenants sharing same cache mechanism having an amount of data storage space, wherein a first cache tenant having a first cache size is allocated a first cache space within the data storage space, and wherein a second cache tenant having a second cache size is allocated a second cache space within the data storage space. The method further comprises determining cache profiles for at least the first cache tenant and the second cache tenant according to data collected during the monitoring; analyzing the cache profiles for the plurality of cache tenants to determine an expected cache usage model for the cache mechanism; and analyzing the cache usage model and factors related to cache efficiency or performance for the one or more cache tenants to dictate one or more occupancy constraints.

Abstract: Systems and methods for cache optimization, the method comprising monitoring cache access rate for one or more cache tenants in a computing environment, wherein a first cache tenant is allocated a first cache having a first cache size which may be adjusted; determining a cache profile for at least the first cache over one or more time intervals according to data collected during the monitoring, analyzing the cache profile for the first cache to determine an expected cache usage model for the first cache; and analyzing the cache usage model and factors related to cache efficiency for the one or more cache tenants to dictate one or more constraints that define boundaries for the first cache size.

Abstract: A method of allocating servers for range requests includes receiving a range request for items in a database that is distributed across storage devices that are accessible through corresponding servers in a network that includes the storage devices and the servers; and initializing a server-allocation value for the range request, where the server-allocation value specifies a number of servers to allocate for executing the range request. The method further includes executing the range request by allocating the servers and using the allocated servers to provide values from the range request to a client that accesses the network; and updating the server-allocation value while executing the range request to improve a consumption rate for the client by comparing changes in the consumption rate with changes in the number of allocated servers.
