SQL Queries

Use SQL queries to access the data in the store

Overview

On processor initialisation, a set of queries are auto generated which are used to bind Rest API endpoints.

SELECT

The following queries are generated:

1. Select data using pagination either with or without an ingestTime date range.

2. Ability to export the table either by CSV or Parquet format.

3. Query to delete rows from the table between an ingestTime date range.

Example

The below example exports the quotes table within the nasdaq_quotes schema to a local parquet file.

const response = await fetch('/joule/query/nasdaq_quotes/quotes}', {
    method: 'GET',
    headers: {},
});
const data = await response.json();

Read the Data API query page more information on how to access the captured data.
