# QuestDB

QuestDB is a high-performance, open-source SQL database for applications in
financial services, IoT, machine learning, DevOps and observability. It includes
endpoints for PostgreSQL wire protocol, high-throughput schema-agnostic
ingestion using InfluxDB Line Protocol, and a REST API for queries, bulk
imports, and exports.

QuestDB implements ANSI SQL with native extensions for time-oriented language
features. These extensions make it simple to correlate data from multiple
sources using relational and time series joins. QuestDB achieves high
performance from a column-oriented storage model, massively-parallelized vector
execution, SIMD instructions, and various low-latency techniques. The entire
codebase was built from the ground up in Java and C++, with no dependencies, and
is 100% free from garbage collection.

## Try QuestDB

We provide a [live demo](https://demo.questdb.io/) provisioned with the latest
QuestDB release and a 1.6 billion row dataset with 10 years of NYC taxi trips to
query.

To run QuestDB, Docker can be used to get started quickly:

```bash
docker run -p 9000:9000 -p 9009:9009 -p 8812:8812 questdb/questdb
```

macOS users can use Homebrew:

```bash
brew install questdb
brew services start questdb
```

The [QuestDB downloads page](https://questdb.io/get-questdb/) provides direct
downloads for binaries and has details for other installation and deployment
methods.

### Connect to QuestDB

- [Web Console](https://questdb.io/docs/reference/web-console/) listening on
  port `9000`
- [REST API](https://questdb.io/docs/reference/api/rest/) on port `9000`
- [PostgreSQL](https://questdb.io/docs/reference/api/postgres/) wire protocol on
  port `8812`
- [InfluxDB](https://questdb.io/docs/reference/api/influxdb/) line protocol for
  high-throughput ingestion on port `9009`

## How QuestDB compares to other open source TSDBs

Here are high-cardinality
[Time Series Benchmark Suite](https://questdb.io/blog/2021/06/16/high-cardinality-time-series-data-performance/)
results using the `cpu-only` use case with 6 workers on an AMD Ryzen 3970X:

The following table shows query execution time of a billion rows run on a
`c5.metal` instance using 16 of the 96 threads available:

| Query                                                        | Runtime    |
| ------------------------------------------------------------ | ---------- |
| `SELECT sum(double) FROM 1bn`                                | 0.061 secs |
| `SELECT tag, sum(double) FROM 1bn`                           | 0.179 secs |
| `SELECT tag, sum(double) FROM 1bn WHERE timestamp in '2019'` | 0.05 secs  |
