Developer docs

This section explains how driver internals work. The intended audience is:

• driver developers and contributors;
• framework authors, or architects who want to write advanced customizations and integrations.

Most of this material will involve “internal” packages; see API conventions for more explanations.

We recommend reading about the common infrastructure first. Then the documentation goes from lowest to highest level:

• Native protocol layer: binary encoding of the TCP payloads;
• Netty pipeline: networking and low-level stream management;
• Request execution: higher-level handling of user requests and responses;
• Administrative tasks: everything else (cluster state and metadata).

If you’re reading this on GitHub, the .nav file in each directory contains a suggested order.
