Data storage scheme switching in a distributed data storage system

A computer-implemented method comprising:

• storing a first content item in a distributed data storage system according to a first data storage scheme;
• using one or more trained machine learning models to compute, based on a first set of one or more historical accesses to the first content item in the distributed data storage system while the first content item is stored in the distributed data storage system according to the first data storage scheme, a first probability that the first content item will be accessed in the distributed data storage system during a first period of time;
• and
• based on the first probability, storing the first content item in the distributed data storage system according to a second data storage scheme.

A non-transitory computer-readable media comprising instructions which, when executed by a computing system, causes the computing system to perform:

• storing a plurality of content items in a distributed data storage system according to a first data storage scheme;
• using one or more trained machine learning models to compute, for each content item of the plurality of content items, based on a respective set of one or more historical accesses to the content item in the distributed data storage system when stored according to the first data storage scheme, a respective probability that the content item stored according to the first data storage scheme will be accessed in the future;
• and
• based on the respective probability computed for each content item of the plurality of content items, maintaining storage of the content item according to the first data storage scheme or switching the content item to a second data storage scheme.
