Dynamic erasure coding

A non-transitory computer readable medium having stored thereon a sequence of instructions which, when executed by a processor causes a set of acts, the set of acts comprising:

• accessing a fault tolerance policy attribute describing a fault tolerance policy associated with a computing system;
• accessing a computing node topology attribute that describes a location of a computing node of the computing system;
• generating a plurality of candidate erasure coding configurations, wherein the candidate erasure coding configurations are generated based at least in part on at least one of, the fault tolerance policy attribute or the computing node topology attribute;
• computing respective configuration scores corresponding to respective candidate erasure coding configurations of the plurality of candidate erasure coding configurations;
• and
• selecting an erasure coding configuration from the plurality of candidate erasure coding configurations, the selecting being based at least in part on the respective configuration scores.
