Description

Index group interface allows:

• indexes on the same table to receive centralized lifecycle events called secondary index groups. Sharing of data between multiple column indexes on the same table allows SAI disk usage to realise significant space savings over other index implementations.
• index-group to analyze user query and provide a query plan that leverages all available indexes within the group.
