Indexing Tables
Tables can be indexed with these indexing tools:
- Storage-attached indexes (SAI)
-
Storage-attached indexes are attached to SSTables in Cassandra and located on the cluster that a SSTable is located.
- SSTable-attached indexes (SASI)
-
SSTable-attached indexes are generated with SSTables in Cassandra and located on the node that a SSTable is located.
- Secondary indexes (2i)
-
Secondary indexes (2i) are indexes that are written on each node in a Cassandra cluster and must be read from the node.
