Object headers facilitating storage of data in a write buffer of a storage system

A method comprising:

• receiving a request to write a given data object to a write buffer of at least one storage system;
• allocating an entry in the write buffer for storage of the given object;
• generating a header for the given data object, the header comprising a first portion indicating a validation status of the given data object;
• writing the header for the given data object to the allocated entry of the write buffer with the first portion of the header comprising a value indicating an invalid status for the given data object;
• writing the given data object to the allocated entry of the write buffer;
• and
• updating the header of the allocated entry by modifying the value of the first portion of the header to indicate a valid status for the given data object responsive to a successful write of the given data object to the allocated entry of the write buffer;
• wherein the method is implemented by at least one processing device comprising a processor coupled to a memory.

A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device causes said at least one processing device:

• to receive a request to write a given data object to a write buffer of at least one storage system;
• to allocate an entry in the write buffer for storage of the given object;
• to generate a header for the given data object, the header comprising a first portion indicating a validation status of the given data object;
• to write the header for the given data object to the allocated entry of the write buffer with the first portion of the header comprising a value indicating an invalid status for the given data object;
• to write the given data object to the allocated entry of the write buffer;
• and
• to update the header of the allocated entry by modifying the value of the first portion of the header to indicate a valid status for the given data object responsive to a successful write of the given data object to the allocated entry of the write buffer.
