Vector Database Migration, Benchmarking, and Capacity Planning

Move vector workloads safely with clear benchmarks, capacity plans, and schema designs that preserve quality, latency, and cost.

Vector DB migrations require careful benchmarking (recall/latency/cost), schema compatibility, capacity planning, and rollback strategies to avoid quality regressions and downtime.

Filters on metadata; mixed precision; varying k.

Failure tests: node loss, region failover, compaction.

Recall@k/NDCG, latency P50/P95, QPS, tail under faults.

Metadata columns with appropriate types and filters.

Collections per tenant; sharding/replication; TTL for stale vectors.

Create target clusters; sync schemas; enable TLS/auth.

Frequently asked questions

What is the recommended approach to estimating query throughput (QPS) and anticipating future growth, while also ensuring sufficient headroom for peak loads?

Estimate QPS and growth; headroom for peak x2–x3.

How should memory and SSD storage be sized based on the specific type of index being used, considering compaction overhead?

Memory/SSD sizing per index type; compaction overhead.

What strategies should be employed for autoscaling, partitioning, and region placement to minimize latency?

Autoscaling/partition strategies; region placement for latency.

How can a recall regression be identified and addressed, particularly concerning ‘golden queries’ and proactive alerting?

Recall regression: golden queries; alert on drops; keep dual-read until stable.
