| <div class="paragraph"> |
| <p>Cassandra 5.0 introduces vector search, which leverages storage-attached indexing and dense indexing techniques to transform data exploration and analysis. This update is especially impactful for domains like machine learning and artificial intelligence (AI). <em><a href="https://www.youtube.com/watch?v=Bxc-JLRx450&list=PLqcm6qE9lgKKls90MlpejceYUU_0qVnWa&index=10" target="_blank" rel="noopener">Watch this video about Vector Search</a></em>.</p> |

| <div class="paragraph"> |
| <p>Cassandra 5.0 introduces new dynamic data masking (DDM) capabilities which allow you to obscure sensitive information using a concept called masked columns. DDM doesn’t change the stored data. Instead, it just presents the data in its redacted form during SELECT queries.</p> |
