Amazon QLDB Launches Index Improvements

Amazon QLDB launches index improvements to create indexes on non-empty tables. QLDB Indexes accelerate data retrieval and previously, all indexes needed to be created at the time of table creation. As customer data volumes grow, new data access patterns are required to meet business and performance requirements. Now, customers can utilize QLDB's index improvements to build new indexes on their existing tables, providing greater flexibility. Amazon QLDB is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log. Amazon QLDB can be used to track each and every application data change and maintains a complete and verifiable history of changes over time.
