Deep dive and wrap up
Play this lessonThis lesson comes with a live-code challenge and a chapter quiz.41 bits hold at most 2⁴¹ − 1 = 2,199,023,255,551 milliseconds, which is about 69 years. So a Snowflake generator works for ~69 years after its custom epoch. A recent epoch delays overflow; after 69 years we need a new epoch or a migration.
