REFUSED_STREAM error from the server

[lakshgupta]

Hi

I deployed the Sqlflite docker container and am exploring Flight SQL protocol currently. I was hoping to use SQLFlite to be able to execute a query to DuckDB using a Flight SQL client. In my test, I am running into the following error:

org.apache.arrow.flight.FlightRuntimeException: UNAVAILABLE: RST_STREAM closed stream. HTTP/2 error code: REFUSED_STREAM

The query works once in a while after several attempts. My client code is in Java and I have tried the following methods, both of them have the same behavior.

• flightClient.listActions(callOptions) // not flightSqlClient
• flightSqlClient.execute(query, callOptions)

I am not sure what is the cause of the issue. Is there any setting/configuration I am missing in the setup? What information I can collect to debug the problem?

DuckDB version = v1.1.1
Arrow version on server = 17.0.0
