Overview
Flake ids are represented in 64-bit unsigned integers. Ids can be broken down into three components:
- Bucket: A 10-bit bucket id for sharding ids over 1024 different buckets.
- Timestamp: A 42-bit millisecond encoded timestamp of when the id was generated.
- Sequence: A 12-bit incrementing sequence number that is reset at each timestamp increment.
With this formation, flake can generate 4096 unique ids per millisecond per bucket, or in other words, 4 billion unique ids per second. For reference, YouTube gets about 75 thousand unique views per second.
