Zvec (zvec v0.4.0)

Elixir bindings for zvec, an in-process vector database.

Quick Start

schema =
  Zvec.Schema.new("demo")
  |> Zvec.Schema.add_field("text", :string)
  |> Zvec.Schema.add_vector("embedding", 384, index: %{type: :hnsw, metric_type: :cosine})

{:ok, col} = Zvec.Collection.create_and_open("/tmp/mydb", schema)

doc = Zvec.Doc.new("doc1", %{
  "text" => "hello world",
  "embedding" => Zvec.Query.float_list_to_binary(List.duplicate(0.1, 384))
})

:ok = Zvec.Collection.insert(col, [doc])
:ok = Zvec.Collection.optimize(col)

{:ok, results} = Zvec.Collection.query(col,
  Zvec.Query.vector("embedding", List.duplicate(0.1, 384), topk: 5))
