nornicdb-qdrant-migration

nornicdb-qdrant-migration is a skill for Claude Code, Codex from orneryd/NornicDB. It costs 101 tokens per session (1,825 once invoked), scanned A, original, MIT.

A migration guide for moving vector search data from Qdrant to NornicDB through a compatible gRPC connection. It covers collections, vectors, nodes, batches, and count checks.

In plain words
What is it for?
Use it to plan and run a partial or complete Qdrant-to-NornicDB migration, including connection setup, authentication, vector configuration, batch writes, and verification.
Why use it?
It removes the need to build a protocol bridge or invent a database schema conversion. It also identifies data that does not transfer, such as snapshots and HNSW indexes.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

nornicdb-qdrant-migration 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 1mo ago.

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.

Migrating from Qdrant to NornicDB

NornicDB's Qdrant-compatible gRPC service means migration is a same-API replay: the source and target speak the same wire, so the script reading from Qdrant can write into NornicDB through the same client library. There is no protocol bridge to build, no schema translation to invent.

This skill covers the migration surface itself. Runnable scripts are in scripts/migration/qdrant/.

Prerequisites

  1. Enable the gRPC server on NornicDB. Off by default:
    export NORNICDB_QDRANT_GRPC_ENABLED=true
    export NORNICDB_QDRANT_GRPC_LISTEN_ADDR=":6334"
    
  2. Match dimension limits. If your source has vectors above 4096, raise NORNICDB_QDRANT_GRPC_MAX_VECTOR_DIM before running.
  3. Match auth. If your source enforces auth, your migration script needs an API key (Qdrant) and your target needs the same if Auth.Enabled=true.

Migration phases

1. List source collections

Use the source SDK's standard collection listing:

  • Python: client.get_collections().collections
  • Go: client.ListCollections(ctx)
  • Node: client.getCollections().collections

Pick a subset with a --collections a,b flag if the migration is partial.

2. Replicate vector config per collection

Read the source collection's VectorParams (or named-vector dict/map) and apply them to NornicDB. Both sides accept the same shape:

client.create_collection(
    collection_name="docs",
    vectors_config=m.VectorParams(size=1024, distance=m.Distance.COSINE),
)

Named-vector collections are passed as a dict/map where each entry has its own size and distance. NornicDB stores each named vector independently in node.NamedEmbeddings[<vectorName>].

If the target already has a collection of the same name, skip the create with --skip-existing.

3. Stream points and upsert

Scroll source points in batches and upsert into target:
