# :baby_chick: quackpipe
_QuackPipe is a serverless OLAP API built on top of DuckDB emulating and aliasing the ClickHouse HTTP API_
Play with DuckDB SQL and Cloud storage though a familiar API, without giving up old habits and integrations.
### :hatched_chick: Demos
:hatched_chick: try a [sample s3/parquet query](https://quackpipe.fly.dev/?user=default#U0VMRUNUCiAgICB0b3duLAogICAgZGlzdHJpY3QsCiAgICBjb3VudCgpIEFTIGMsCkZST00gcmVhZF9wYXJxdWV0KCdodHRwczovL2RhdGFzZXRzLWRvY3VtZW50YXRpb24uczMuZXUtd2VzdC0zLmFtYXpvbmF3cy5jb20vaG91c2VfcGFycXVldC9ob3VzZV8wLnBhcnF1ZXQnKQpXSEVSRSByZWFkX3BhcnF1ZXQudG93biA9PSAnTE9ORE9OJwpHUk9VUCBCWQogICAgdG93biwKICAgIGRpc3RyaWN0Ck9SREVSIEJZIGMgREVTQwpMSU1JVCAxMA==) in our [miniature playground](https://quackpipe.fly.dev) _(fly.io free tier, 1x-shared-vcpu, 256Mb)_
:hatched_chick: launch your own _free instance_ on fly.io
### :seedling: Get Started
Download a [binary release](https://github.com/metrico/quackpipe/releases/), use [docker](https://github.com/metrico/quackpipe/pkgs/container/quackpipe) or build from source
#### 🐋 Using Docker
```bash
docker pull ghcr.io/metrico/quackpipe:latest
docker run -ti --rm -p 8123:8123 ghcr.io/metrico/quackpipe:latest
```
#### 📦 Download Binary
```bash
curl -fsSL github.com/metrico/quackpipe/releases/latest/download/quackpipe-amd64 --output quackpipe \
&& chmod +x quackpipe
```
##### 🔌 Start Server w/ parameters
```bash
./quackpipe --port 8123
```
##### 🔌 Start Server w/ file database, READ-ONLY access
```bash
./quackpipe --port 8123 --params "/tmp/test.db?access_mode=READ_ONLY"
```
##### 🔌 Start Server w/ Motherduck authentication token
###### Using DuckDB Params
```bash
./quackpipe --port 8123 --params "/tmp/test.db?motherduck_token=YOUR_TOKEN_HERE"
```
###### Using System ENV
```bash
export motherduck_token=''
./quackpipe --port 8123
```
Run with `-h` for a full list of parameters
##### Parameters
| params | usage | default |
|-- |-- |-- |
| `--port` | HTTP API Port | `8123` |
| `--host` | HTTP API Host | `0.0.0.0` |
| `--stdin` | STDIN query mode | `false` |
| `--format` | FORMAT handler | `JSONCompact` |
| `--params` | Optional Parameters | |
#### :point_right: Playground
Execute stateless queries w/o persistence using the embedded playground
##### 👉 Stateful Queries
Execute stateful queries with data persistence by adding unique HTTP Authentication. No registration required.
#### :point_right: API
Execute queries using the POST API
```
curl -X POST https://quackpipe.fly.dev
-H "Content-Type: application/json"
-d 'SELECT version()'
```
#### :point_right: STDIN
Execute queries using STDIN
```
# echo "SELECT 'hello', version() as version FORMAT CSV" | ./quackpipe --stdin
hello,v1.1.1
```
### :fist_right: Extensions
Several extensions are pre-installed by default in [Docker images](https://github.com/metrico/quackpipe/blob/main/Dockerfile#L9), including _parquet, json, httpfs_
When using HTTP API, _httpfs, parquet, json_ extensions are automatically pre-loaded by the wrapper.
Users can pre-install extensions and execute quackpipe using a custom parameters:
```
echo "INSTALL httpfs;" | ./quackpipe --stdin --params "?extension_directory=/tmp/"
./quackpipe --port 8123 --host 0.0.0.0 --params "?extension_directory=/tmp/"
```
### 
ClickHouse HTTP
Quackpipe can be used to query a remote instance of itself and/or ClickHouse using the HTTP API
```sql
CREATE OR REPLACE MACRO quackpipe(query, server := 'https://play.clickhouse.com', user := 'play', format := 'JSONEachRow') AS TABLE
SELECT * FROM read_json_auto(concat(server, '/?default_format=', format, '&user=', user, '&query=', query));
SELECT * FROM quackpipe("SELECT number as once, number *2 as twice FROM numbers(10)")
```
### ClickHouse UDF
Quackpipe can be used as [executable UDF](https://clickhouse.com/docs/en/engines/table-functions/executable) to get DuckDB data IN/OUT of ClickHouse queries:
```sql
SELECT *
FROM executable('quackpipe -stdin -format TSV', TSV, 'id UInt32, num UInt32', (
SELECT 'SELECT 1, 2'
))
Query id: dd878948-bec8-4abe-9e06-2f5813653c3a
┌─id─┬─num─┐
│ 1 │ 2 │
└────┴─────┘
1 rows in set. Elapsed: 0.155 sec.
```
🃏 What is this? Think of it as a SELECT within a SELECT with a different syntax.
🃏 Format confusion? Make DuckDB SQL feel like ClickHouse with the included [ClickHouse Macro Aliases](https://github.com/metrico/quackpipe/blob/main/aliases.sql)
