# About querying

This section provides general information about querying using the ALM Octane REST API.

In this topic:

## Overview

Data from the query is returned in the JSON format unless specified otherwise in the individual reference. You can specify a supported data format with an ACCEPT header.

A GET request that returns a large amount of data can stress the database server and cause performance degradation for all users.

## Minimizing the load

Here are some ways to minimize the load of a GET request.

- Specify how the returned data are paged. See Page data (limit, offset, total_count).

- Retrieve only the fields you need by using a fields clause. See Select fields (fields)

  Filter the instances to be returned with a query clause. See Query.

Tip: You can set the order in which resources are returned. See Sort results (order_by).
