Write ordering for persistent memory

A node comprising:

• a memory storing instructions;
• and
• a processor coupled to the memory, the processor configured to execute the instructions to cause the node to:
• create a first group of actions to commit to persistent memory of the node in any order while retaining an ability to reconstruct the persistent memory into a consistent state;
• identify existing data, within the persistent memory, that is to be overwritten by data being written by an action of the first group;
• track, within a log, tracked data used to reconstruct the persistent memory into the consistent state, wherein the tracked data includes the existing data or the data being written by the action;
• write the data into the persistent memory according to a byte-addressable format;
• and
• in response to detecting the node recovering from a failure, initiate a reconstruction process that utilizes the tracked data within the log to reconstruct the persistent memory into the consistent state.

A non-transitory machine readable medium comprising instructions for performing a method, which when executed by a node, causes the node to:

• create a first group of actions to commit to persistent memory of the node in any order while retaining an ability to reconstruct the persistent memory into a consistent state;
• identify existing data, within the persistent memory, that is to be overwritten by data being written by an action of the first group;
• track, within a log, tracked data used to reconstruct the persistent memory into the consistent state, wherein the tracked data includes the existing data or the data being written by the action;
• write the data into the persistent memory according to a byte-addressable format;
• and
• in response to detecting the node recovering from a failure, initiate a reconstruction process that utilizes the tracked data within the log to reconstruct the persistent memory into the consistent state.
