Method and system for efficiently reading a partitioned directory incident to a serialized process

A non-transitory computer readable storage medium having stored thereon, computer executable instructions that, if executed by a computer system cause the computer system to perform a method of reading data from an actual partitioned directory of a hierarchical structure, said method comprising:

• receiving a first read operation and a first offset value from an operating system;
• identifying a first data block in a modeled fully partitioned directory, wherein said first data block is associated with a first subdirectory, and wherein said identifying is based on said first offset value and further based on a predetermined number of entries associated with a buffer;
• determining whether said first data block in said fully partitioned directory is present in said actual partitioned directory;
• writing null values in said buffer if said first data block in said fully partitioned directory is not present in said actual partitioned directory;
• and
• reading said first data block associated with said actual partitioned directory if said first data block in said fully partitioned directory is present in said actual partitioned directory and writing said first data block associated with said actual partitioned directory in said buffer in response to said reading.

A system for reading data from an actual partitioned directory, said system comprising:

• a first memory component operable to store an operating system thereon;
• a buffer associated with said operating system, wherein said buffer has a predetermined number of entries;
• a second memory component operable to store said actual partitioned directory;
• a third memory component operable to store a file system thereon, wherein said file system is operable to:
• receive first read operation and a first offset value from said operating system;
• identify a first data block in a modeled fully partitioned directory, wherein said first data block is associated with a first subdirectory, and wherein said identifying is based on said first offset value and further based on a predetermined number of entries associated with said buffer;
• determine whether said first data block in said fully partitioned directory is present in said actual partitioned directory;
• write null values in said buffer if said first data block in said fully partitioned directory is not present in said actual partitioned directory;
• and
• write said first data block associated with said actual partitioned directory in said buffer if said first data block in said fully partitioned directory is present in said actual partitioned directory.
