RANGE INDEXED DATA ACCESS

A big file.
One small read.

Turn JSON records into a static RIDA dataset. Its index finds a value, and the reader asks an HTTP server or CDN for that byte range.

Your JSON.
Your choice of runtime.

Install RIDA for Python or run it with Node.js. Build datasets on your computer and read them locally or from your own CDN.

01 / PYTHON

One simple install.

Use Python 3.10 or newer with pip.

pip install rida-format

Open the command guide

rida --help

The package name is rida-format. In Python code, use import rida.

Encryption support is included in this install. You can build and read encrypted datasets without another install command.

02 / NODE.JS

Run it with npx.

Use Node.js 20 or newer. npm and npx come with a standard Node.js installation.

npx rida-format --help

npx downloads the package when needed and runs the command. You do not need to install it globally first.

Prefer a shorter command?

Install globally, then use the package name directly:

npm install -g rida-format
rida-format --help

Use it inside your Node.js project

npm install rida-format

Import RidaReader from rida-format in your Node.js application or server. Encryption support is included.

THE IDEA

Put the catalog with the reader.

The only file served by your CDN is the data. The index already knows where a requested value lives, so opening a dataset costs no request.

01

Source JSON

Objects, arrays or folders of standard JSON records.

02

RIDA files

Data, index, optional map and private key.

03

One small read

HTTP 206 returns the exact value range.

START HERE

A real guide, not a pitch.

Use the RIDA library in your own application and host its data with a provider you choose. These guides cover the 0.3.3 library, CLI and file format; no RIDA hosting subscription is required.

01File format

Four files, codecs, catalog layout, IDs and the lookup algorithm.

02Build

Install, scan, choose dense or sparse, combine groups and publish.

03Read

Local files, HTTP URLs, cache, get_many and range-server rules.

04Measured results

Reference dataset sizes, latency and provider delivery estimates.
