Memory Backends

Murd Operation

Murd Memory

A Murd Memory object is made up of at least a "ROW" and "COL" element. These two elements together are treated as a unique identifier for the storage location of the element. Taken together, ideal candidates for the value of 'ROW' and 'COL' are URIs, UUIDs, UTC timestamps, GPS coordinates, and the like.

{
    "ROW":{part of unique identifier},
    "COL":{part of unique identifier},
    "{ARBITRARY_KEY}": "{ARBITRARY_VALUE}"
    ...
}
