Aggregation of read requests requesting common data objects into a common read operation in a data storage system for improving throughput

A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions readable and/or executable by a computer to cause the computer to perform a method comprising:

• suspending a parent/control thread of a data storage system;
• receiving, by the computer, a plurality of read requests, each read request having storage information associated therewith;
• adding, by the computer, read requests that are received while a parent/control thread is suspended, to a hash/list structure;
• analyzing, by the computer, the added read requests, wherein the analyzing includes sorting the read requests using the associated storage information;
• aggregating, by the computer, read requests requesting common data objects into a common read operation;
• stopping aggregation of the read requests requesting the common data objects into the common read operation in response to a determination that an amount of data unnecessarily read when retrieving data associated with the common read operation exceeds a predefined wasted space value;
• and
• dispatching, by the computer, the common read operation to a multi-threaded I/O layer of the data storage system for retrieving data associated with the read requests.

A system, comprising:

• a processor;
• and
• logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to:
• suspend a parent/control thread of a data storage system;
• receive a plurality of read requests while the parent/control thread is suspended, each read request having storage information associated therewith;
• add the read requests, that are received while the parent/control thread is suspended, to a hash/list structure;
• analyze the added read requests, wherein the analyzing includes sorting the read requests using the associated storage information;
• aggregate read requests requesting common data objects into a common read operation;
• stop aggregation of the read requests requesting the common data objects into the common read operation in response to a determination that a container value associated with a most previously aggregated read request has changed;
• and
• dispatch the common read operation to a multi-threaded I/O layer of the data storage system for retrieving data associated with the read requests.
