Flow logs data incompatibilities in error tables that it defines on source files. Flow defines the error tables in the Object File System.
Error limits for source files are specified by the global directive max_errors, which is 10 by default. You can change the max_errors setting from the VantageCloud Lake Console (see Creating a Flow Using the Console (AWS)).
An error table defined on Parquet source files is unlikely to capture data incompatibilities. A Parquet source field can cause an error only if it is incorrectly mapped to a target column, which is a configuration error, not a runtime error.
