Snowflake ID Throughput & Pricing

Based on 241 − 1 = 2,199,023,255,551 ms timestamp epoch (~69 years). Each ID = 8 bytes.

2,199,023,255,551 ms ÷ 1000 ÷ 60 ÷ 60 ÷ 24 ÷ 365 ≈ 69.73 years · 241 − 1

Note: 8 bytes/ID = raw 64-bit integer. Actual DB storage (indexes, WAL, MVCC) typically 3–5× higher. Timestamp epoch governs ID uniqueness window — independent of storage capacity.
