You can now use the VECTOR_INDEX.STATISTICS function to calculate how much an indexed table's data has drifted between when a vector index was created and the present. If table data has changed enough to require a vector index rebuild, you can use the ALTER VECTOR INDEX REBUILD statement to rebuild the vector index without downtime. These features are generally available (GA).
