Field Details

UTF_8

public static final Charset UTF_8

DAY

public static final long DAY

Notably, the cassandra implementation has day granularity

TODAY

public static final long TODAY

FRONTEND

public static final Endpoint FRONTEND

BACKEND

public static final Endpoint BACKEND

DB

public static final Endpoint DB

KAFKA

public static final Endpoint KAFKA

CLIENT_SPAN

public static final Span CLIENT_SPAN

Only for unit tests, not integration tests. Integration tests should use random trace IDs.

TRACE

public static final List<Span> TRACE

Only for unit tests, not integration tests. Integration tests should use random trace IDs.

LOTS_OF_SPANS

public static final Span[] LOTS_OF_SPANS

Zipkin trace ids are random 64bit numbers. This creates a relatively large input to avoid flaking out due to PRNG nuance.
