Caching for data store clients

An information processing system comprising:

• a storage client comprising an integrated cache for reducing a number of accesses to a storage service of a plurality of storage services;
• a memory;
• and
• a processor communicatively coupled to the memory and to the storage client, wherein the processor, responsive to executing computer instructions, performs operations comprising:
• providing an interface for using a storage service via the storage client;
• implementing the interface within the storage client, the interface implemented for each of a plurality of storage services;
• associating an object expiration time with at least one object stored in the cache;
• keeping the at least one object in the cache after the object expiration time has passed;
• selecting, by an application, through the interface via the storage client at least one storage service in the plurality of storage services and using the at least one storage service via the interface within the storage client;
• monitoring a latency for data accesses from the storage client to the at least one storage service of the plurality of storage services;
• increasing an amount of caching in response to determining based on the monitored latency for data accesses that the latency is increasing;
• and
• decreasing the amount of caching in response to determining based on the monitored latency for data accesses that the latency is decreasing.

A non-transitory computer readable storage medium, comprising computer instructions which, responsive to being executed by a processor cause the processor to perform operations, the processor being in an information processing system comprised of a memory communicatively coupled with the processor, and a storage client comprising an integrated cache for reducing a number of accesses to a storage service of a plurality of storage services, and wherein the processor, responsive to executing the computer instructions, performs operations comprising:

• providing an interface for using a storage service via the storage client;
• implementing the interface for each of a plurality of storage services;
• associating an object expiration time with at least one object stored in the cache;
• keeping the at least one object in the cache after the object expiration time has passed;
• selecting, by an application, through the interface via the storage client at least one storage service in the plurality of storage services and using the at least one storage service via the interface within the storage client;
• monitoring a latency for data accesses from the storage client to the at least one storage service of the plurality of storage services;
• increasing an amount of caching in response to determining based on the monitored latency for data accesses that the latency is increasing;
• and
• decreasing the amount of caching in response to determining based on the monitored latency for data accesses that the latency is decreasing.
