Why ANN index is only supported on Duplicate Key table model ? #61712
Description
In this website: https://doris.apache.org/docs/4.x/ai/vector-search/overview, section “Usage Limitation”, it says:
ANN index is only supported on Duplicate Key table model.
Why ANN index cannot be supported on Unique key table model and Aggregate key table model ?
Is there any plan to let ANN index support Unique key table model or Aggregate key table model ?
