Guarantee timestamp. This instructs Milvus to see all operations performed before a provided timestamp. If no such timestamp is provided, then Milvus will search all operations performed to date. [0]:
Graceful time. Only used in bounded consistency level. If graceful_time is set, PyMilvus will use current timestamp minus the graceful_time as the guarantee_timestamp. This option is 5s by default if not set. [5]:
