How to flush and wait for traces to be updated to server.

[ajeeth-b]

I run all the data from datasets, and map the dataset item and trace to another process to evaluate based on the traces.

when I run each data set I do, langfuse_client.flush()

To get traces I have to get from langfuse using client.

langfuse_client: Langfuse = Client()
langfuse_client.get_traces(trace_id)

I get langfuse.api.resources.commons.errors.not_found_error.NotFoundError, because it is not reflected in the server yet.
error ss

Now How do I wait until the flush is done and reflected in the server?

Hey @ajeeth-b! I'm here to help you squash bugs, answer questions, and become a contributor. Let's tackle this together! 🤖

To ensure that langfuse_client.flush() is complete and the traces are reflected on the server before retrieving them with langfuse_client.get_traces(trace_id), you should use the flush method to manually flush the events. This method ensures that all events are sent to the server immediately. Here is how you can do it:

# Assuming you have a langfuse client instance
langfuse_client.flush()

# Now you can safely retrieve the traces
traces = langfuse_client.get_traces(trace_id)

The flush method will log an error and retry the batch in case of network issues, ensuring that the traces are sent before you attempt to retrieve them ^[1].

Currently, there is a delay of 15-30 seconds until traces can be fetched from the API again. You'll need to add a delay + retry with some backoff here. We are making changes to reduce this.

See note

New data is typically available for querying within 15-30 seconds of ingestion, though processing times may vary at times. Please visit status.langfuse.com if you encounter any issues.
