LexoRank is a ranking system introduced by Atlassian JIRA.

-

Background
----------

[](#background)

What is the best representation of an ordered list in a database? With a dumb order number based ranking system, re-ordering a row of a list may require updating all rows of the list in a transaction, which is O(n).

-
-

LexoRank makes it O(1). All you need to do is updating the re-ordered row's order field.
