Abstract

Embodiments include method, systems and computer program products for enhanced storage clients. In some embodiments, an interface for using a storage service may be provided. The interface for each of a plurality of storage services may be implemented within a storage client. A cache may be integrated within the storage client for reducing a number of accesses to a storage service of the plurality of storage services. A compression method may be provided in the storage client to reduce a size of data objects. An encryption method may be provided in the storage client to preserve data privacy. An application may select at least one storage services of the plurality of storage services and using the at least one storage service via the storage client.

Claims

1. A computer-implemented method comprising:

providing an interface for using a storage service;

implementing the interface for each of a plurality of storage services within a storage client;

integrating a cache within the storage client for reducing a number of accesses to a storage service of the plurality of storage services;

providing a compression method in the storage client to reduce a size of data objects;

providing an encryption method in the storage client to preserve data privacy; and

an application selecting at least one storage service of the plurality of storage services and using the at least one storage service via the storage client.

2. The computer-implemented method of claim 1, further comprising:

in response to the at least one storage service being unresponsive or responding too slowly, the application using the cache to allow the application to continue without communicating with the at least one storage service.

3. The computer-implemented method of claim 1, further comprising:

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 the latency increasing; and

decreasing the amount of caching in response to the latency decreasing.

4. The computer-implemented method of claim 1, further comprising:

varying a frequency of compressing data from the computer program based on assessing costs and benefits of compressing the data.

5. The computer-implemented method of claim 1, further comprising:

storing a data object in the at least one storage service;

for each of a plurality of updates to the data object, storing a delta corresponding to each of the plurality of updates in the at least one storage service, wherein the delta encodes a difference between a new version of the data object and a previous version of the data object; and

storing a complete updated version of the data object in the at least one storage service in response to at least one of;

(1) a number of deltas from the previous version of the data object exceeds a first threshold;

(2) a total size of deltas from the previous version of the data object exceeds a second threshold;

(3) the client determines that a cost of determining an updated version of the data object by applying deltas to the previous version exceeds a third threshold.

6. A computer program product comprising a non-transitory storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:

providing an interface for using a storage service;

implementing the interface for each of a plurality of storage services within a storage client;

integrating a cache within the storage client for reducing a number of accesses to a storage service of the plurality of storage services;

providing a compression method in the storage client to reduce a size of data objects;

providing an encryption method in the storage client to preserve data privacy; and

an application selecting at least one storage service of the plurality of storage services and using the at least one storage service via the storage client.

7. The computer program product of claim 6, the method further comprising:

in response to the at least one storage service being unresponsive or responding too slowly, the application using the cache to allow the application to continue without communicating with the at least one storage service.

8. The computer program product of claim 6, the method further comprising:

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 the latency increasing; and

decreasing the amount of caching in response to the latency decreasing.

9. The computer program product of claim 6, the method further comprising:

varying a frequency of compressing data from the computer program based on assessing costs and benefits of compressing the data.

10. The computer program product of claim 6, the method further comprising:

storing a data object in the at least one storage service;

for each of a plurality of updates to the data object, storing a delta corresponding to each of the plurality of updates in the at least one storage service, wherein the delta encodes a difference between a new version of the data object and a previous version of the data object; and

storing a complete updated version of the data object in the at least one storage service in response to at least one of;

(1) a number of deltas from the previous version of the data object exceeds a first threshold;

(2) a total size of deltas from the previous version of the data object exceeds a second threshold;

(3) the client determines that a cost of determining an updated version of the data object by applying deltas to the previous version exceeds a third threshold.

11. A system, comprising:

a processor in communication with one or more types of memory, the processor configured to;

provide an interface for using a storage service;
