In the Jaeger UI http://localhost:16686/search, there is an option to upload JSON files for traces.
I wonder can we download the traces from Jaeger itself and use them in the future for finding performance issues?
How can we do that, I see no option to download traces from Jaeger Ui.
When you open an individual trace in the Jaeger UI, there is a View dropdown in the top right corner. One of the options is to view/download the given trace as a JSON file.
You can also programmatically query the Jaeger query service via JSON/Protobuf API, but those endpoints will not result in a data format that you can load back into the UI.

See the answer on this jaeger issue, you will need to query elastic search or the source where the data is stored.
Alternatively, you should raise an issue on jaeger-ui detailing your case.
