Build a Bento memory store in 15 minutes

Spin up Postgres

docker run -d --name bento-pg -e POSTGRES_PASSWORD=postgres -p 5432:5432 pgvector/pgvector:pg17

Create the schema

create extension if not exists vector;
create table memories (
  id bigserial primary key,
  body text not null,
  embedding vector(1536) not null,
  inserted_at timestamptz not null default now()
);
create index memories_emb_idx on memories using hnsw (embedding vector_cosine_ops);

Seed three memories

Embed three short documents with the model of your choice and insert them.

Ask the first question

Point Bento’s /v1/ask at the database and ask it something only those three documents would know. The point isn’t the answer — it’s that the memory survived a restart, joins to the rest of your data, and respects whatever row-level security you put in front of it.

End the tutorial with pnpm bento:deploy to push your store to Northflank.
