nathanielc opened a new issue, #6644: URL: https://github.com/apache/arrow-rs/issues/6644
**Describe the bug** <!-- A clear and concise description of what the bug is. --> When using the FlightDataEncoder the DictionaryHandling logic does not recuse into fields of a Map type. As a result any dictionary within a Map is not hydrated and can therefore break encoding as multiple dictionaries are sent. **To Reproduce** <!-- Steps to reproduce the behavior: --> 1. Using FlightDataEncoder encode two batches where there is a Map with a dictionary for either the key or value field. 2. An error occurs as the error_on_replacement check inside the FlightIPCEncoder fails as a dictionary is replaced **Expected behavior** <!-- A clear and concise description of what you expected to happen. --> The FlightDataEncoder correctly hydrates the dictionaries to avoid the encoding error **Additional context** <!-- Add any other context about the problem here. --> PR with a fix incoming. -- This is an automated message from the Apache Git Service.
