Delayed Log Write of Input/Outputs Using Persistent Memory

A system, comprising:

• at least one processor;
• and
• at least one memory that stores executable instructions that, when executed by the at least one processor, facilitate performance of operations, comprising:
• maintaining a data storage system, wherein the data storage system comprises a persistent memory and chunk storage, wherein the persistent memory is more performant than the chunk storage according to at least one defined performance metric, wherein the chunk storage stores data in chunks of a fixed-size, and wherein respective chunks of the chunks correspond to respective parity values;
• associating a persistent memory stream with a logical inode of the persistent memory, wherein the persistent memory stream has a fixed size;
• based on receiving a request associated with a storage client to write data to the data storage system, writing the data to the persistent memory concurrently with writing the data to the chunk storage, wherein the writing of the data to the persistent memory comprises utilizing the logical inode for successive data writes until the persistent memory stream is filled;
• and
• after completing the writing of the data to the persistent memory and before completing the writing of the data to the chunk storage, sending an indication, to the storage client, that the data has been successfully stored in the data storage system.
