Tables can be indexed with these indexing tools:
- Storage-attached indexes (SAI)
Storage-attached indexes are attached to SSTables in Apache Cassandra® and located on the cluster that a SSTable is located.
- Secondary indexes (2i)
Secondary indexes (2i) are indexes that are written on each node in a Apache Cassandra® cluster and must be read from the node.
- DSE Solr Search indexes
DSE Solr Search indexes are indexes built on the Solr nodes in a DataStax Enterprise (DSE) cluster.
