SDK overview

SDK overview

Cognite has a large number of Software Development Kits (SDKs), both adapted to specific programming languages and to specific use cases. All Cognite SDKs are open-source and available on Github, and contributions are welcome.

Types of SDKs and toolkits

The SDKs are split into three types: the general SDKs for interacting with the Cognite Data Platform, the SDKs for interacting with the Cognite Data Fusion platform APIs giving you access to the common functionality of the platform, the core resource types, and the management of data. The specialized SDKs that offers a more tailored experience for specific tasks or areas. And then finally, the industry SDKs that exposes more industry-specific functionality.

Our SDKs and toolkits have a special target group in mind based on the language and what they are meant to be used for. This means that functionality will be exposed slightly differently in the different SDKs, and not all SDKs will have the same functionality.

Support and maintenance

The two main generic SDKs for CDF are the Python and the JavaScript SDKs, for primarily backend and frontend respectively, but the Python SDK is also used from the Jupyter Notebook and Streamlit-powered web experiences, and the JS SDK is used from Node.js.

The Python SDK is the most mature and feature-rich SDK with the most users, but all the SDKs listed here are actively maintained.

Most of the SDKs and toolkits are community-supported with contributions from Cognite engineers, and we encourage you to contribute.

General SDKs

Python

The Python SDK is targeted towards general usage of CDF for Python developers. It also has special support for high-throughput jobs (for data engineers) and for many data scientist tasks. You will most likely find what you need in this SDK.

JavaScript

The JavaScript SDK is primarily for web developers who want to build frontend applications. Most usage is React-based, but Angular can also be used. The GraphQL API is also available for use in any JavaScript application with a standard GraphQL client.

Java

The Java SDK is focused on backend developers and data engineers who want to build high-throughput applications. It is an alternative to the Python SDK.

Scala

The Scala SDK is used in CDF's transformation engine. It is thus primarily focused on shifting large amounts of data.

.NET

The .NET SDK is an asynchronous SDK for .NET developers and is used in CDF's OData service powering the PowerBI integration. It is thus focused on queries and analytics. It can be used from C# and F#.

Rust

The Rust SDK supports the core CDF resource types as well as data modeling.

Specialized SDKs

Reveal 3D viewer

The Reveal 3D viewer is an embeddable JavaScript library for visualizing big 3D models on the web. It supports complex CAD models and large point clouds.

Spark Data Source

The Spark data source lets you read and write data from and to CDF in parallel using asynchronous calls with Apache Spark.

Geospatial SDK

The Geospatial SDK allows you to operate on the powerful geospatial APIs in CDF using Python.

Industry SDKs

Well Data Layer

The JavaScript Well Data Layer gives you access to the powerful well APIs in CDF from frontend applications. Well bores, trajectories, logs, and more are native in the library.

Well Data Layer

The Python Well Data Layer gives you access to the powerful well APIs in CDF from backend applications. Well bores, trajectories, logs, and more are native in the library.

Seismic SDK

The Seismic SDK for Python allows you to use the seismic APIs of CDF. You can ingest SEG-Y files into CDF, structure the data in partions, and query the data using the SDK.

Toolkits

Extractor utils

The extractor utils toolkit for Python makes it really easy to build an extractor for CDF. It handles everything, including caching of state, batchwise ingestion, monitoring heartbeat, logging, and more.

CDF Toolkit

The CDF toolkit is a Python library and CLI for interacting with CDF and load and delete datasets. It can also be used as a reference for how to use common CDF Python SDK functions.
