The Aerospike Database and its client API have been refined over a decade to support mission-critical deployments, offering developers a comprehensive understanding of its architecture and capabilities. The system's architecture includes data distribution across clusters, transaction support, and server-side execution of complex data types, with data organized into namespaces and sets. Aerospike's Smart Client, which supports multiple programming languages, simplifies application development by managing complex tasks like request routing and data distribution. The API accommodates complex data types and operations, allowing server-side execution to minimize data transfers. Aerospike ensures atomicity in single-record transactions and offers multiple processing modes to balance performance and complexity. Performance enhancements include the use of primary and secondary indexes, batch and multi-op requests, and support for expressions and User Defined Functions. The database supports flexible data persistence, expiration policies, and metadata operations, with a strong emphasis on high performance and efficient data modeling. Additionally, useful libraries like the Document API and Java Object Mapper facilitate easier data management and application integration.
