reconcilation of schemas work only if missing columns are in the end. For eg: Commit1: Schema: col1, col2, col3, col4 Commit2: Schema: col1, col2, col3, col4, col5, col6 Commit3: old writer. Schema: col1, col2, col3, col4 Commit3 will succeed when you enable reconcile schema config. In general, adding new colunmns at the end of existing schema works. it may break if you try to add new columns inbetween. for eg, in commit2, if your schema as col1, col5, col6, col2, col3, col4, your write or read may break. -- This is an automated message from the Apache Git Service.
