> Its also cool to see that it works on the local object store, but the output appears duplicated: @nuno-faria thanks for giving this a test run! Looking at this output I initially thought you were correct that it was duplicated, but on closer inspection the duration of the operations is different between the first and the 2nd case. This leads me to believe the object_store operations may actually get executed twice for some reason. Generating the text output currently leverages a `drain` iterator behind a mutex on the underlying data, so getting any duplication seems unlikely (although if someone can identify how this might be possible that would be an excellent find). Perhaps we've just uncovered some curious behavior in DataFusion? -- This is an automated message from the Apache Git Service.
