Index rebuild capacity in the stated retrieval case
about 2.0 TBderived
| Value kind | derived — Derived values are guide calculations; their result is only as fixed as the stated inputs, scope, and method. |
|---|---|
| Scope | Assumes 100 million 768-dimension FP32 vectors plus 96 GB of graph and metadata allowances per index, two replicas, a full old/new rebuild overlap and 20% free capacity. |
| As of | 2026-09 |
| Source | Worked example in Chapter 9.7; assumptions stated in the text. |
| Derivation | (100000000 × 768 × 4 / 1e9 + 64 + 32) × 2 replicas × 2 generations / .8 / 1000 = 2.016 TB. |
