Optimized storage caching for computer clusters using metadata

A computer system, comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method for managing computer jobs in a queue comprising:
• extracting metadata from a new job received for processing;
• extracting current metadata from a new job received for processing;
• determining when a similar enriched metadata exists in a database;
• determining a job score associated with said new job based on said extracted metadata and any existing enriched metadata;
• determining a storage footprint for said new job based on said extracted metadata;
• determining whether said new job can be grouped and labelled similarly for processing with any other jobs disposed on a queue;
• and
• adding said new job to said queue and sorting said queue, wherein a placement of said new job on said queue is based on a combination of said new job's score and a storage footprint, and said new job's grouping with other jobs disposed on said queue for processing and any existing similar enriched metadata.

A computer program product, comprising:

• one or more non-transitory computer-readable storage media and program instructions stored on at least one of the one or more tangible storage media, the program instructions executable by a processor to cause the processor to perform a method comprising:
• extracting current metadata from a new job received for processing;
• determining when a similar enriched metadata exists in a database;
• determining a job score associated with said new job based on said extracted metadata and any existing enriched metadata;
• determining a storage footprint for said new job based on said extracted metadata;
• determining whether said new job can be grouped and labelled similarly for processing with any other jobs disposed on a queue;
• and
• adding said new job to said queue and sorting said queue, wherein a placement of said new job on said queue is based on a combination of said new job's score and a storage footprint, and said new job's grouping with other jobs disposed on said queue for processing and any existing similar enriched metadata.
