Optimizing data placement based on data temperature and lifetime prediction

A system comprising:

• data processing hardware;
• and
• memory hardware in communication with the data processing hardware, storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
• monitoring one or more access patterns for a data object over a period of time, the data object stored at a first storage device of a plurality of storage devices, each respective storage device of the plurality of storage devices comprising corresponding storage parameters different from each other storage device of the plurality of storage devices;
• predicting, using a model and based on the one or more access patterns, an updated object temperature of the data object and an updated object lifetime of the data object, the updated object temperature representing a frequency of access for the data object;
• selecting, based on the updated object temperature, the updated object lifetime, and the corresponding storage parameters of the plurality of storage devices, a second storage device of the plurality of storage devices, the corresponding storage parameters of the second storage device are different from the corresponding storage parameters of the first storage device;
• and
• moving the data object from the first storage device to the second storage device.
