How Dovetail powers Multi-Tenant Agents with Vector Indexing at Scale

What this session is about

When you're building multi-tenant vector search but can't control what customers throw at you, every indexing decision — isolation, embedding, chunking, partitioning — becomes a bet you're making blind, and this talk gives you the framework to make the right ones.

Editorial commentary · what to actually do about this on Monday

The concept
Multi-tenant vector search has a four-axis decision tree: isolation, embedding choice, chunking strategy, partitioning. Each is a bet you're making blind unless you frame it explicitly.
Why it matters
Customer A's bizarre 10,000-page PDF cannot be allowed to performance-tax customer B's queries. In B2B SaaS, this is non-negotiable.
The hard parts
Tenant isolation in shared indexes is hard. Tenant-per-index is operationally simple but doesn't scale past a few hundred tenants. Tenant-aware filtering inside a shared index is harder to get right but is the only path that scales.
Playbook moves
(1) Adopt tenant-aware filtering at the index level, not the application level. (2) Pre-decide who controls embedding model upgrades — you, or the customer? Both have valid arguments. (3) Cap per-tenant index size to bound worst-case latency.
The surprise
Most teams optimise for retrieval *quality* and forget *tail latency*. A single cold tenant with a giant document set will kill P99 for everyone unless you isolate aggressively. Per-tenant query budgets are a feature, not a limitation. ---
