qdrant-scaling

A guide for deciding how to expand Qdrant when the amount of data, number of searches, response time, or number of customers grows. Qdrant is a database used to find similar items by meaning.

In plain words
What is it for?
Use it to plan capacity, choose between vertical and horizontal scaling, and decide how to handle larger indexes, faster search, or more tenants.
Why use it?
Different growth problems need different solutions, such as a larger machine or multiple machines. It helps identify what is actually limiting the system before choosing a scaling approach.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

qdrant-scaling scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Qdrant Scaling

Usage

You say What happens
"CodeIntel's index is getting huge / search is slow at scale" Determine first whether it's data-volume, QPS, or tenant-count growth (below) — CodeIntel today is single-node/single-operator, so most scaling questions here start from a from-scratch decision, not an existing cluster.
Ambiguous/no specific scaling question Ask what's actually growing (data volume vs. query throughput vs. tenant count) before recommending vertical vs. horizontal scaling.

First determine what you're scaling for:

  • data volume
  • query throughput (QPS)
  • query latency
  • query volume

After determining the scaling goal, we can choose scaling strategy based on tradeoffs and assumptions. Each pulls toward different strategies. Scaling for throughput and latency are opposite tuning directions.

Scaling Data Volume

This becomes relevant when volume of the dataset exceeds the capacity of a single node. Read more about scaling for data volume in Scaling Data Volume

Scaling for Query Throughput

If your system needs to handle more parallel queries than a single node can handle, then you need to scale for query throughput.

Read more about scaling for query throughput in Scaling for Query Throughput

Scaling for Query Latency

Latency of a single query is determined by the slowest component in the query execution path. It is in sometimes correlated with throughput, but not always. It might require different strategies for scaling.

Read more about scaling for query latency in Scaling for Query Latency

Scaling for Query Volume

By query volume we understand the amount of results that a single query returns. If the query volume is too high, it can cause performance issues and increase latency.

Tuning for query volume is opposite might require special strategies.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
