Why Use the Data Client Library

The Data Client Library allows you to:

• Manage access credentials for your project
• Get and modify catalog metadata
• Get and publish stream, volatile, and versioned data

The Data Client Library provide asynchronous APIs, streaming, backpressure, and parallelism support, and includes built-in retries/resumes. The Data Client Library is a multi-module library that has both lower level building blocks and higher level APIs. There are also Pekko Streams connectors to selected technologies, protocols and libraries.
