# base_async_handler

## GalileoAsyncBaseHandler

Async Callback handler for logging traces to the Galileo platform.

**Arguments**

* `_galileo_logger` (`GalileoLogger`): The Galileo logger instance.

* `_nodes` (`dict[UUID, Node]`): A dictionary of nodes, where the key is the run\_id and the value is the node.

* `_start_new_trace` (`bool`): Whether to start a new trace when a chain starts. Set this to `False` to continue using the current trace.

* `_flush_on_chain_end` (`bool`): Whether to flush the trace when a chain ends.

### async\_commit

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

Commit the nodes to the trace using the Galileo Logger. Optionally flush the trace.

### async\_end\_node

```python theme={null}
async def async_end_node(self, run_id: UUID, **kwargs: Any) -> None
```

End a node in the chain. Commit the nodes to a trace if the run\_id matches the root node.

**Arguments**

* `run_id` (`UUID`): The run ID.
* `**kwargs` (`Any`): Additional parameters to update the span with.
