Abstract

A method for providing a partition aware quality of service feature may include receiving an indication of data to be stored in a distributed memory grid, determining a quality of service policy rule to be applied in relation to storage of the data in the memory grid based on the indication, and initiating storage of data blocks of the data in the memory grid. The data blocks may be provided with corresponding partition identifiers that facilitate retrieval of the data by indicating a location of storage of respective ones of the data blocks within the memory grid. The method may further include providing a quality of service token in association with the partition identifier based on the quality of service policy rule.

Claims

1. A method comprising:

receiving an indication of data to be stored in a distributed memory grid;

determining a quality of service policy rule to be applied in relation to storage of the data in the memory grid based on the indication;

initiating storage of data blocks of the data in the memory grid, the data blocks provided with corresponding partition identifiers that facilitate retrieval of the data by indicating a location of storage of respective ones of the data blocks within the memory grid; and

providing a quality of service token in association with the partition identifier based on the quality of service policy rule.

2. The method of claim 1, wherein determining the quality of service policy rule comprises referencing a routing table associating the indication with a corresponding policy rule.

3. The method of claim 1, wherein determining the quality of service policy rule comprises referencing a routing table associating metadata associated with the indication with a corresponding policy rule.

4. The method of claim 1, wherein determining the quality of service policy rule comprises utilizing an assignment algorithm generating the quality of service policy rule based on the indication.

5. The method of claim 1, wherein determining the quality of service policy rule comprises utilizing an assignment algorithm generating the quality of service policy rule based on metadata associated with the indication.

6. The method of claim 1, further comprising enabling replication of the data blocks based on the quality of service policy rule.

7. The method of claim 1, wherein determining the quality of service policy rule comprises determining at least one of availability, consistency, speed of access, and a performance guarantee.

8. The method of claim 1, further comprising enabling routing of a request associated with the data based on the quality of service policy rule.
