Configure AWS Advanced JDBC Wrapper connection pooling with the assistant

A deep-dive into connection pooling for the AWS Advanced JDBC Wrapper on Amazon Aurora and RDS. Covers the plugin-based architecture, the fundamental difference between external pooling (above the wrapper, pooling logical connections) and internal pooling (below the wrapper, pooling physical connections per instance), and when each approach is appropriate. Internal pooling excels with read/write splitting, leastConnections load balancing, and smoother failover, while external pooling (e.g., HikariCP) is simpler for standard Spring Boot apps without R/W splitting. Also introduces JDBC-WRAPPER-CONFIGURATION-ASSISTANT, a generative AI assistant for AWS Advanced JDBC Wrapper 4.0+ that helps choose settings, review configurations, and diagnose issues through Greenfield, Review, and Skip-the-interview modes. Includes detailed configuration examples, plugin compatibility tables, IAM token TTL pitfalls, multi-cluster clusterId isolation, and a decision guide.
