Vantage uses fastpath delete processing when the target table has a simple or aggregate join index that is one of the following:
  • Single-table join index.
  • Multitable join index defined with an inner join.
  • Multitable join index where the table being deleted is the outer table of an outer join.
This includes the following statements:
  • A DELETE ALL or unconditional DELETE statement on a table that has a simple or aggregate join index. Vantage uses fastpath delete processing for the base table and its join index.
  • A conditional DELETE statement on a table that has a simple or aggregate join index. Vantage uses fastpath delete processing only for the join index if the DELETE condition covers the entire index.
