Hi Yuxia, Two questions:
1. Are you expecting all DynamicTableSinks to support Truncate? The FLIP could use some explanation for what supporting and not supporting the operation means. 2. How will truncate inoperate with streaming queries? That is, if I truncate an input to a streaming query, is there any defined behavior?
