ScratchDB

ScratchDB is a wrapper around Clickhouse that lets you input arbitrary JSON and perform analytical queries against it. It automatically creates tables and columns when new data is added.

Quickstart

1. Run the server

Clone the repo:

$ git clone git@github.com:scratchdata/ScratchDB.git
$ cd ScratchDB

Start clickhouse and localstack:

$ docker-compose up

In a separate terminal, start the insert service:

$ go run . insert

Finally, in an additional terminal window, start the ingest service:

$ go run . ingest

2. Insert JSON data

$ curl -X POST http://localhost:3000/data \
    -H 'Content-Type: application/json' \
    -H 'X-Api-Key: local' \
    -d '{"table":"my_table","data":{"fruit": "apple"}}'

3. Query

To view data in JSON format: http://localhost:3000/query?q=select * from my_table

curl -H 'X-Api-Key: local' "http://localhost:3000/query?q=select%20*%20from%20my_table"

To view data in an HTML table: http://localhost:3000/query?format=html&q=select * from my_table

curl -H 'X-Api-Key: local' "http://localhost:3000/query?format=html&q=select%20*%20from%20my_table"
