> Introduce an interface {{OMHashCodeGenerator}} which translates each of the {{OBJECT_STORE "OBS"}} bucket layout key path names into a hash code based on the corresponding hash function used. The write operations on different key paths now have their corresponding hash codes and are allotted a thread writer (executor) index for execution determined via the modulo ({{{}hashCode % om.num.concurrent.write.threads{}}}) - this enables concurrency for write operations.
