Delayed allocation for data object creation

A system comprising:

• a memory;
• a processing device operatively coupled to the memory, the processing device to:
• receive a request to create a data object;
• store a first portion of the data object in a buffer in a first data storage;
• determine a location in a second data storage in view of a predicted size of the data object;
• migrate the first portion of the data object from the buffer to the location in the second data storage;
• and
• in response to receiving a second portion of the data object, directly store the second portion in the second data storage.

A non-transitory machine-readable storage medium storing instructions that cause a processing device to:

• store a first portion of a data object in a buffer in a first data storage comprising volatile memory;
• determine a location in a second data storage in view of a predicted size of the data object, wherein the second data storage comprises non-volatile memory;
• migrate, by the processing device, the first portion of the data object from the buffer to the location in the second data storage;
• and
• store the second portion in the second data storage directly.
