Secondary index group API
SAI uses an extension of the Cassandra secondary index API to
- allow 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.
