Spring Data Aerospike version 4.6.0 introduces several key features and enhancements, including native support for Aerospike keys, paginated queries, and custom query creation mechanisms. The new configuration parameter `keepOriginalKeyTypes` allows developers to control how primary keys are stored in the database. Paginated queries can be used to retrieve specific pages of data from large datasets, allowing for more efficient and scalable querying. Custom query creation mechanisms, such as using Qualifier and Query objects, enable developers to build complex queries in a readable and maintainable way. These features aim to improve the overall performance and flexibility of Spring Data Aerospike, making it easier for developers to work with Aerospike databases.
