LakeQL
  1. Data Sources

Data Sources

Connect LakeQL to your data stack through adapters and the datasource contract.

A data source is how LakeQL reaches a query engine. This section covers the datasource contract, the built-in adapters (Trino, Fabric), writing data, and storage operations.

Overview

What a data source is, and the contract every adapter implements.

Writing

How LakeQL persists data — the two choices that define a write.

Storage

The object-storage operations behind the external-storage write strategy.

Trino

The Trino adapter — connection, write config, metadata, and capabilities.

Fabric

The Microsoft Fabric adapter — connection, metadata, and capabilities.
