### emit

```python theme={null}
def emit(self, span: ReadableSpan) -> None
```

Enqueue a completed span without flushing the batch.

Return the current receiver-acknowledgement health snapshot.

### force\_flush

```python theme={null}
def force_flush(self, timeout_millis: int=30000) -> bool
```

Drain all registered processors through the owned provider.

### shutdown

```python theme={null}
def shutdown(self) -> None
```

Shut down the owned provider exactly once.

## build\_batch\_processor

```python theme={null}
def build_batch_processor(exporter: SpanExporter,
                          config: BatchConfig | None=None) -> BatchSpanProcessor
```

Build a BatchSpanProcessor with explicit SDK defaults.

## build\_span\_sink

```python theme={null}
def build_span_sink(exporter: SpanExporter,
                    batch_config: BatchConfig | None=None) -> SpanSink
```

Build an SDK-owned sink without replacing the global tracer provider.
