Optimization of cached persistent volumes in containerized environments

A computer system, comprising:

• a processor set;
• one or more computer-readable storage media;
• and
• program instructions stored on the one or more computer-readable storage media, the program instructions executable by the processor set to cause the processor set to:
• receive a first request for a provision of a specific cached persistent volume (PV) within a first environment, wherein the first request comprises at least one specific directory path associated with at least a first dataset, and wherein the first request is associated with a retrieval of the at least first dataset for an application from a second environment;
• identify a set of cached persistent volumes (PVs) from a plurality of cached PVs based on:
• a presence of a match between the first request and the set of cached PVs, and a sharing status associated with each cached PV of the plurality of cached PVs, wherein the sharing status indicates an availability of a respective cached PV of the plurality of cached PVs for allocation, and wherein the plurality of cached PVs is deployed within the first environment;
• determine a set of directory paths associated with the identified set of cached PVs, wherein each directory path of the set of directory paths is indicative of at least a second dataset stored within each cached PV of the set of cached PVs in the first environment, and wherein each cached PV of the identified set of cached PVs is associated with at least one directory path of the set of directory paths;
• generate a set of matching scores for the set of cached PVs based on the determined set of directory paths and the at least one specific directory path associated with the first request, wherein each matching score of the set of matching scores is indicative of a degree of the match between the first request and a respective cached PV of the set of cached PVs;
• control an allocation of a cached PV of the set of cached PVs to the application based on the generated set of matching scores;
• obtain a first portion of the at least first dataset from the cached PV of the set of cached PVs based on the degree of the match;
• and
• transmit the first portion of the at least first dataset to the application.

A computer-program product for controlling an allocation of a cached persistent volume (PV) to an application, the computer-program product comprising:

• one or more computer-readable storage media;
• and
• program instructions stored on the one or more computer-readable storage media to perform operations comprising:
• receiving a first request for provisioning of a specific cached PV within a first environment, wherein the first request comprises at least one specific directory path associated with a first dataset, and wherein the first request is associated with a retrieval of the first dataset for the application from a second environment;
• identifying a set of cached persistent volumes (PVs) from a plurality of cached PVs based on:
• a presence of a match between the first request and the set of cached PVs, and a sharing status associated with each cached PV of the plurality of cached PVs, wherein the sharing status indicates an availability of a respective cached PV of the plurality of cached PVs for allocation, and wherein the plurality of cached PVs is deployed within the first environment;
• determining a set of directory paths associated with the identified set of cached PVs, wherein each directory path of the set of directory paths is indicative of a second dataset stored within each cached PV of the set of cached PVs in the first environment, and wherein each cached PV of the identified set of cached PVs is associated with at least one directory path of the set of directory paths;
• generating a set of matching scores for the set of cached PVs based on the determined set of directory paths and the at least one specific directory path associated with the first request, wherein each matching score of the set of matching scores is indicative of a degree of the match between the first request and a respective cached PV of the set of cached PVs;
• identifying a cached PV from the set of cached PVs based on the generated set of matching scores, wherein a matching score associated with the identified cached PV is highest among the generated set of matching scores, and wherein the specific cached PV is excluded from the set of cached PVs;
• and
• controlling the allocation of the identified cached PV to the application based on the generated set of matching scores.
