Method, device and computer program product for storing metadata

An electronic device for storing metadata, comprises:

• a processor;
• and
• a memory having computer program instructions stored thereon, the processor executing the computer program instructions in a memory to control the electronic device to perform acts comprising:
• identifying, based on a set of metadata items to be stored, a first plurality of key-value pairs and a second plurality of key-value pairs, each key-value pair including a metadata item from the set of metadata items and a keyword corresponding to the metadata item;
• causing a first co-routine to utilize available computing resources to process the first plurality of key-value pairs to store the first plurality of key-value pairs in a storage device;
• and
• in response to an amount of computing resources available for the first co-routine to process the first plurality of key-value pairs being below a first threshold amount of available computing resources, causing a second co-routine to process the second plurality of key-value pairs to store the second plurality of key-value pairs in the storage device, wherein the second co-routine is different from the first co-routine.

A computer program product being stored on a non-transitory computer-readable medium and comprising machine-executable instructions which, when executed, cause a machine to perform operations, comprising:

• identifying, based on metadata items to be stored, a first group of key-value pairs and a second group of key-value pairs, each key-value pair including a metadata item from the metadata items and a keyword corresponding to the metadata item;
• causing a first co-routine to utilize available computing resources to process the first group of key-value pairs to store the first group of key-value pairs in a storage device;
• and
• in response to an amount of computing resources available for the first co-routine to process the first group of key-value pairs being below a first threshold amount of available computing resources, causing a second co-routine to process the second group of key-value pairs to store the second group of key-value pairs in the storage device, wherein the second co-routine is different from the first co-routine.
