org.apache.polaris.service.tracing.DefaultRequestIdGenerator

All Implemented Interfaces:

RequestIdGenerator

@ApplicationScoped
public class DefaultRequestIdGenerator
extends Object
implements RequestIdGenerator

Default implementation of RequestIdGenerator, striking a balance between randomness and performance.

The IDs generated by this generator are of the form: UUID_COUNTER. The UUID part is randomly generated at startup, and the counter is incremented for each request.

In the unlikely event that the counter overflows, a new UUID is generated and the counter is reset to 1.
