## Limitations

126+
The current preview has the following limitations:
127+
124128
- No partition support. Vector index can't be partitioned.
125129
- The table must have a single integer non-nullable column clustered index.
126130
- During and for all the time needed for vector index creation to complete, an SCH-M lock is acquired on the table. As a result, the lock prevents any access to the table or its metadata.
127131
- Once a vector index is created on a table, the table becomes read-only. No data modification is allowed while the vector index is present on the table.
132+
- Vector index are not replicated to subscribers
