Systems and methods for retrieving data

A system for retrieving data, the system comprising:

• a receiving module, stored in memory, that receives a request to retrieve a plurality of data segments from a storage system that stores the plurality of data segments in a plurality of data containers;
• an obtaining module, stored in memory, that obtains, for each data segment from the plurality of data segments, information that indicates which data container from the plurality of data containers stores the data segment;
• a determination module, stored in memory, that determines, based on the information that indicates which data container stores each data segment, that using an initial access order to retrieve the plurality of data segments would result in visiting one or more data containers from the plurality of data containers more than one time;
• a rearranging module, stored in memory, that rearranges access to one or more data segments from the plurality of data segments such that retrieving the plurality of data segments results in visiting the one or more data containers at least one fewer times than the one or more data containers would be visited using the initial access order, wherein the rearranging module rearranges access to the one or more data segments by grouping access to the one or more data segments, the grouping comprising:
• sorting the initial access order by one or more data container identifiers;
• and
• merging visits to a same data container in the plurality of data containers such that each data container in the plurality of data containers is visited a single time when the plurality of data segments are retrieved;
• a retrieving module, stored in memory, that retrieves the plurality of data segments from the storage system based on the rearranged access order;
• at least one physical processor configured to execute the receiving module, the obtaining module, the determination module, the rearranging module, and the retrieving module.

A non-transitory computer-readable medium comprising one or more computer-readable instructions that, when executed by at least one processor of a computing device, cause the computing device to:

• receive a request to retrieve a plurality of data segments from a storage system that stores the plurality of data segments in a plurality of data containers;
• obtain, for each data segment from the plurality of data segments, information that indicates which data container from the plurality of data containers stores the data segment;
• determine, based on the information that indicates which data container stores each data segment, that using an initial access order to retrieve the plurality of data segments would result in visiting one or more data containers from the plurality of data containers more than one time;
• rearrange access to one or more data segments from the plurality of data segments such that retrieving the plurality of data segments results in visiting the one or more data containers at least one fewer times than the one or more data containers would be visited using the initial access order, wherein rearranging access to the one or more data segments comprises grouping access to the one or more data segments, the grouping comprising:
• sorting the initial access order by one or more data container identifiers;
• and
• merging visits to a same data container in the plurality of data containers such
• that each data container in the plurality of data containers is visited a single time when the plurality of data segments are retrieved;
• retrieve the plurality of data segments from the storage system based on the rearranged access order.
