All Known Implementing Classes:

DbClientTracing, DbCounter, DbMeter, DbTimer

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface DbInterceptor
```
Interceptor to handle work around a database statement. Example of such interceptors: tracing, metrics.
Interceptors can be defined as global interceptors, interceptors for a type of a statement and interceptors for a named statement. These are executed in the following order:
1. Named interceptors - if there are any interceptors configured for a specific statement, they are executed first
2. Type interceptors - if there are any interceptors configured for a type of statement, they are executed next
3. Global interceptors - if there are any interceptors configured globally, they are executed last
Order of interceptors within a group is based on the order they are registered in a builder, or by their priority when loaded from a Java Service loader
