Currently, CREATE VECTOR INDEX disables mutations that would modify the vector index (e.g. INSERT, DELETE & UPDATE statements on the vector column) until backfill is complete. In order to allow online creation of vector indices, we need to either implement merge from the temporary index for backfill or enable writes to go directly to the vector index as it is backfilled.
