The data that you insert will go through a process before it is finally saved: Initially, it will flow in as data streams. Then, it will be stored in segments as entities. Milvus will select an appropriate growing segment to store the data in streams until the segment reaches its upper limit and becomes sealed.
However, it's important to note that the row count displayed may not match the number of records that were inserted because data in streams is not taken into account.
EXCEPTIONS:
-
MilvusException
This exception will be raised when any error occurs during this operation.
