# PostgreSQL Nostr Relay Architecture Analysis
This document summarizes common approaches and best practices for building Nostr relays backed by PostgreSQL, based on industry-standard designs and existing open-source relay implementations.
## Identified Projects
* **Nostrss**: High-performance Rust-based relay.
* **Nostrgres**: Focused on PostgreSQL integration with complex event filtering.
* **Relay-rs (Postgres branch)**: General purpose high-throughput relay.
## Detailed Analysis
### 1. Common Schema Patterns
* **Event Storage (JSONB)**: Most PostgreSQL-backed relays store the raw event as a JSONB object in a central `events` table. This provides flexibility for the evolving Nostr spec while allowing efficient extraction of fields.
* **Tag Denormalization**: While the raw event is in JSONB, performant relays extract tags (like `p`, `e`, `t`, `d`) into a separate `tags` table with foreign key relationships to the `events` table. This avoids slow JSONB traversal during complex filter queries.
* **Author/Publisher Tracking**: A dedicated `authors` or `pubkeys` table is typically used to maintain indexing on the `pubkey` field, enabling quick lookups of user activity.
### 2. Performance Optimization
* **GIN Indexes on JSONB**: Crucial for filtering on specific event tags or custom properties stored within the event object. GIN indexes with `jsonb_path_ops` are generally preferred for equality checks.
* **Time-Series Partitioning**: Given the append-only nature of Nostr, partitioning the `events` table by time (e.g., daily or weekly chunks) is highly recommended. This significantly improves query performance for recent data and simplifies data expiration/deletion.
* **Clustering**: Clustering the `events` table by the timestamp index can reduce disk I/O, as it keeps temporally related events physically adjacent on the disk.
### 3. Schema Management Approaches
* **Migrations**: Most mature relays utilize migration tools (like `Flyway`, `Diesel migrations`, or `Golang-migrate`) to version control database schema changes. This is critical for production stability.
* **Auto-generation**: Some lightweight prototypes auto-generate schemas at startup. This is generally discouraged for production due to the risk of destructive changes, data loss, or blocking DDL operations on large tables.
## Recommendations for Building a New Relay
1. **Prioritize Denormalization**: Do not rely solely on JSONB queries for high-traffic filters. Extract indexed tags into dedicated columns or tables.
2. **Use Partitioning from Day One**: Implementing native PostgreSQL partitioning (e.g., using `pg_partman`) is much easier before the dataset grows to millions of rows.
3. **Connection Pooling**: PostgreSQL requires aggressive connection management. Use a high-performance pooler like `PgBouncer` to handle the large number of concurrent, short-lived connections common in WebSocket-based relay traffic.
4. **Asynchronous Writes**: Decouple the WebSocket ingestion thread from the database writer thread to ensure that slow database writes do not impact the relay's responsiveness.
## Schema Definitions
### Relay-rs (Postgres)
```sql
-- Events table
CREATE TABLE "event" (
id bytea NOT NULL,
pub_key bytea NOT NULL,
created_at timestamp with time zone NOT NULL,
kind integer NOT NULL,
"content" bytea NOT NULL,
hidden bit(1) NOT NULL DEFAULT 0::bit(1),
delegated_by bytea NULL,
first_seen timestamp with time zone NOT NULL DEFAULT now(),
expires_at timestamp(0) with time zone,
CONSTRAINT event_pkey PRIMARY KEY (id)
);
CREATE INDEX event_created_at_idx ON "event" (created_at,kind);
CREATE INDEX event_pub_key_idx ON "event" (pub_key);
CREATE INDEX event_delegated_by_idx ON "event" (delegated_by);
CREATE INDEX event_expires_at_idx ON "event" (expires_at);
-- Tags table
CREATE TABLE "tag" (
id int8 NOT NULL GENERATED BY DEFAULT AS IDENTITY,
event_id bytea NOT NULL,
"name" varchar NOT NULL,
value bytea NULL,
value_hex bytea NULL,
CONSTRAINT tag_fk FOREIGN KEY (event_id) REFERENCES "event"(id) ON DELETE CASCADE,
CONSTRAINT unique_constraint_name UNIQUE (event_id, "name", value, value_hex)
);
CREATE INDEX tag_event_id_idx ON tag USING btree (event_id, name);
CREATE INDEX tag_value_idx ON tag USING btree (value);
CREATE INDEX tag_value_hex_idx ON tag USING btree (value_hex);
-- Account table
CREATE TABLE "account" (
pubkey varchar NOT NULL,
is_admitted BOOLEAN NOT NULL DEFAULT FALSE,
balance BIGINT NOT NULL DEFAULT 0,
tos_accepted_at TIMESTAMP,
CONSTRAINT account_pkey PRIMARY KEY (pubkey)
);
-- Invoice table
CREATE TYPE status AS ENUM ('Paid', 'Unpaid', 'Expired');
CREATE TABLE "invoice" (
payment_hash varchar NOT NULL,
pubkey varchar NOT NULL,
invoice varchar NOT NULL,
amount BIGINT NOT NULL,
status status NOT NULL DEFAULT 'Unpaid',
description varchar,
created_at timestamp,
confirmed_at timestamp,
CONSTRAINT invoice_payment_hash PRIMARY KEY (payment_hash),
CONSTRAINT invoice_pubkey_fkey FOREIGN KEY (pubkey) REFERENCES account (pubkey) ON DELETE CASCADE
);
