Deploy and Host QuestDB on Railway

QuestDB is an open-source time-series database designed for fast ingestion and SQL queries over time-series data. It supports millions of rows per second ingestion via InfluxDB Line Protocol and delivers sub-second query performance on billions of rows — with a built-in web console for immediate SQL access.

About Hosting QuestDB

This template deploys a production-ready QuestDB instance:

Built-in Web Console: SQL editor with autocomplete, schema browser, and chart visualization — no extra UI service needed
Multi-Protocol Access: PostgreSQL wire protocol (port 8812), InfluxDB Line Protocol (port 9009), and REST API — all from a single container
Persistent Storage: Railway volume for database files and WAL (write-ahead log)
High Performance: Columnar storage with SIMD-optimized queries for time-series analytics

Getting Started After Deployment

Accessing the Web Console

After deployment, click on the QuestDB service to find your URL:

Deployments Tab: The URL is displayed directly under the service name
Settings > Networking: Go to Settings tab → scroll to Networking → find Public Networking

Open the URL to access QuestDB's built-in web console — start writing SQL queries immediately.

QuestDB Credentials

The PostgreSQL wire protocol password is auto-generated on deploy. To find it:

Open your Railway project dashboard
Click on the QuestDB service
Go to the Variables tab
Find QDB_PG_PASSWORD — click the eye icon to reveal

Connecting from Your Application

Use any PostgreSQL client to connect via Railway's internal network:

Host: questdb.railway.internal
Port: 8812
User: admin
Password: (from QDB_PG_PASSWORD variable)
Database: qdb

Ingesting Time-Series Data

Send data via InfluxDB Line Protocol from other Railway services:

Host: questdb.railway.internal
Port: 9009

Common Use Cases

Key Features

Built-in Web Console

QuestDB includes a full-featured SQL editor with syntax highlighting, autocomplete, schema browsing, and chart visualization — accessible from your browser without deploying a separate UI service.

Multi-Protocol Ingestion

Ingest data via InfluxDB Line Protocol (ILP) at millions of rows per second, query with standard SQL over PostgreSQL wire protocol, or use the REST API — all from a single deployment.

Time-Series Optimized

Purpose-built columnar storage with SIMD-accelerated query engine. Designated timestamp columns, time-based partitioning, and specialized SQL extensions (SAMPLE BY, LATEST ON, ASOF JOIN) for time-series analytics.

PostgreSQL Compatible

Connect with any PostgreSQL client, ORM, or driver. Works with psql, pgAdmin, DBeaver, and application frameworks like SQLAlchemy, JDBC, and node-postgres.

Persistent Storage

Railway volume ensures database files and WAL survive redeployments. Your data persists across container restarts and updates.
