Efficient erasure coding of mid-size data objects

A method, comprising:

• obtaining, by a system comprising a processor in a node cluster data storage system, object data corresponding to an object to be created and stored in a protected state via erasure coding;
• determining, based on the object data being determined to be of a size greater than or equal to a first size limit and below a second size limit greater than the first size limit, that the object data is to be stored in the protected state without a preliminary protection scheme;
• and
• creating the object in the protected state, comprising:
• dividing the object data into a group of object data fragments;
• erasure encoding the object data into a group of object coding fragments;
• and
• writing the group of object data fragments and the group of object coding fragments into data structure fragments pre-allocated among distributed nodes of a node cluster, wherein the writing the group of object data fragments and the group of object coding fragments to the data structure fragments comprises writing respective object data fragments and object coding fragments to same offset locations in a distributed chunk data structure.

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, the operations comprising:

• receiving object data corresponding to an object to be created and stored in a protected state in a node cluster according to an erasure coding scheme;
• determining, based on a size of the object data, that the object is a mid-size object that does not receive application of a preliminary protection scheme;
• processing the object data into object data fragments and object coding fragments according to the erasure coding scheme;
• writing respective object data fragments of the object data fragments to respective distributed chunk data fragment portions of a distributed chunk data structure that is distributed among nodes of the node cluster;
• and
• writing respective object coding fragments of the object coding fragments to respective distributed chunk coding fragment portions of the distributed chunk data structure, wherein the respective distributed chunk data fragment portions and the respective distributed chunk coding fragment portions have a same offset location in the distributed chunk data structure.
