Interface DatabaseClient

Deprecated.

since 1.2, use Spring R2DBC's DatabaseClient support instead.

@Deprecated
public interface DatabaseClient

A non-blocking, reactive client for performing database calls requests with Reactive Streams back pressure. Provides a higher level, common API over R2DBC client libraries.

Use one of the static factory methods create(ConnectionFactory) or obtain a builder() to create an instance.
