Managing distributed system performance using accelerated data retrieval operations

A non-transitory computer readable storage medium executing computer program instructions for managing performance of a distributed system, the computer program instructions comprising instructions for:

• storing, in a plurality of storage devices of a distributed storage, a plurality of stripes associated with a data item, the plurality of stripes generated according to a coding scheme, wherein the coding scheme generates a number of stripes associated with the data item that is more than a minimum number of stripes needed to assemble the data item, and wherein the plurality of stripes includes at least one redundancy stripe;
• performing a task that requires retrieval of the data item;
• responsive to determining a processing speed of the task does not meet a threshold:
• accelerating retrieval by requesting more than the minimum number of stripes needed to assemble the data item from at least two of the plurality of storage devices of the distributed storage;
• receiving at least the minimum number of stripes;
• and
• assembling the data item from the minimum number of stripes according to the coding scheme.

A system comprising:

• a computer readable storage medium storing processor-executable computer program instructions for managing performance of a distributed system, the instructions comprising instructions for:
• storing, in a plurality of storage devices of a distributed storage, a plurality of stripes associated with a data item, the plurality of stripes generated according to a coding scheme, wherein the coding scheme generates a number of stripes associated with the data item that is more than a minimum number of stripes needed to assemble the data item, and wherein the plurality of stripes includes at least one redundancy stripe;
• performing a task that requires retrieval of the data item;
• responsive to determining a processing speed of the task does not meet a threshold:
• accelerating retrieval by requesting more than the minimum number of stripes needed to assemble the data item from at least two of the plurality of storage devices of the distributed storage;
• receiving at least the minimum number of stripes;
• and
• assembling the data item from the minimum number of stripes according to the coding scheme;
• and
• a processor for executing the computer program instructions.
