FAQ

How does storage billing work?

Storage is billed at $0.33 / GB-month, prorated to the hour. If you halve your data mid-month, you pay half.

When do I need to upgrade from the free tier?

Whenever your usage exceeds the free quota — 2 GB storage, 2 GB writes/month, or 1 PB reads/month. At that point you switch to the Standard plan, which is pay-as-you-go: you pay per unit ($0.33 / GB-month storage, $1.00 / GB writes, $5.00 / PB reads) with no minimum charge. As long as you stay within the free quota, your project stays free forever.

How does partitioning reduce my cost and latency?

Partitioning prevents your queries from scanning the entire index. LambdaDB reads only the partitions you choose, so you pay for fewer bytes scanned and get lower latency. Same index, same accuracy — just faster and cheaper.

What happens when my traffic suddenly spikes?

LambdaDB uses a serverless, disaggregated architecture, so you don't manage clusters yourself. When traffic spikes, we scale up transparently and you only pay for resources actually used — no pre-provisioning for the peak of the peak, no permanently oversized clusters.

How big can a single index get?

LambdaDB scales to billions of vectors in a single logical index at production-scale latency. Sharding and redistribution happen automatically — no manual re-sharding when your dataset grows.
