Of course, what you said is also reasonable, it is ok for me. ``` public static AvroGenericRecordReaderFunction fromTable(Table table, boolean caseSensitive) { return new AvroGenericRecordReaderFunction( table.name(), new Configuration(), table.schema(), null, null, caseSensitive, table.io(), table.encryption()); } ``` Regarding using `FlinkReadOptions`. Essentially, I'm interested in whether it can be built internally, rather than by the user. So far, we've had three ReaderFuntion: `AvroGenericRecordReaderFunction` \ `MetaDataReaderFunction` \ `RowDataReaderFunction`, maybe we'll have new members in the future. Could we provide an enum for the user to choose from and then help build it automatically in the `IcebergSourceBuilder` instead of letting the user create it themselves? -- This is an automated message from the Apache Git Service.
