Last week's solution has been posted here.
This week's challenge explores the problem of Slowly Changing Dimensions, which some of you may be familiar with as you update existing or historical data with changes to those attributes. In this challenge, we'll be updating our log of Jedi rankings to reflect changes in Jedi levels, promotions, and retirements (yes, even the Jedi Knighthood has an HR department).
The challenge's Start file contains an input of the "Current Log", which includes data on an individual's level, when they started at that level, and when they completed that level. Records with an end date indicate either a promotion or a separation for that individual. The input "Today's Updates" includes the changes that take effect today: Bob has joined the Dark Side, Kaitlin and Richard have been promoted up the Jedi Ranks and Joe has joined the Jedi Knighthood. Your task: create a workflow that produces an updated list of the current Jedi ranks.
