Replacing key-value pair sets with new key-value pair sets

A method, comprising:

• selecting a first list of key-value pair sets;
• selecting a second list of key-value pair sets, wherein key-value pair sets in the first list of key-value pair sets are newer than key-value pair sets in the second list of key-value pair sets;
• providing the first list of key-value pair sets and the second list of key-value pair sets to a merge loop process;
• obtaining a first key-value pair and a second key-value pair from the merge loop process;
• forming a new key-value pair set that excludes the first key-value pair and includes the second key-value pair in accordance with a set of rules;
• and
• replacing the second list of key-value pair sets with the new key-value pair set.

A system, comprising:

• memory;
• and
• a controller configured to:
• identify a list of key-value pair sets;
• determine, from the list of key-value pair sets, a key-value pair set, wherein the key-value pair set is an oldest key-value pair set in relation to other key-value pair sets in the list of key-value pair sets;
• identify, from the key-value pair set selected from the list of key-value pair sets, a first key that is included in at least one other key-value pair set from the list of key-value pair sets;
• identify, from the key-value pair set selected from the list of key-value pair sets, a second key that is not included in at least one other key-value pair set from the list of key-value pair sets;
• form a new key-value pair set that excludes the first key and includes the second key;
• and
• replace the key-value pair set selected from the list of key-value pair sets with the new key-value pair set.
