Indexes in Oracle NoSQL Database are data structures that improve the speed of data retrieval operations on a database table.

The SQL for Oracle NoSQL Database query processor can detect which of the existing indexes on a table can be used to optimize the execution of a query. This chapter provides a brief examples-based introduction to index creation, and queries using indexes. For a more detailed description of index creation and usage, see SQL Reference Guide.
