Infrastructure Primitives
Design a Distributed ID Generator (Snowflake)
A coordination-free service producing k-sortable, globally unique 64-bit IDs by combining timestamp, worker ID, and sequence bits.
Open and Simulate this Architecture in InfraDraftCore Architectural Components
Timestamp + Worker ID + Sequence Encoder
Packs three fields into one 64-bit integer, keeping IDs roughly time-sortable.
Worker ID Allocation Service
Assigns unique worker IDs via a coordination service (ZooKeeper/etcd lease) to avoid collisions.
Clock Drift / NTP Guard
Detects backward clock jumps and refuses to generate IDs that could collide.
Per-Node Sequence Counter
In-memory monotonic counter disambiguating multiple IDs within the same millisecond.
Embedded Client SDK
Generates IDs locally with zero network round-trip per ID.
