Connection Handler for Heterogeneous Database Pools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection pool technologies are limited to providing homogeneous connections, making it inefficient and error-prone for applications to manage heterogeneous connections with different configurations, leading to performance degradation and increased resource usage.
Innovation Solution
A connection handler that manages internal heterogeneous connection pools, allowing applications to request and obtain specifically configured connection objects without needing to know the internal pool details, dynamically creating or removing pools as needed to support varying configurations and optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a connection pool provides homogeneous connections with static configuration, then resource management efficiency is improved, but adaptability to heterogeneous connection requirements deteriorates
Solution Approach 1:
The connection pool is segmented into multiple homogeneous sub-pools, each dedicated to a specific connection type or configuration. The pool manager divides the overall connection management task into separate management units, allowing each sub-pool to maintain its own homogeneous connections while collectively serving heterogeneous connection needs.
Solution Approach 2:
The connection pool system is designed with multi-functionality to serve both homogeneous and heterogeneous connection requirements. The pool manager can dynamically select appropriate sub-pools based on connection requests, making the overall system universal enough to handle diverse connection types while maintaining the efficiency benefits of homogeneous sub-pools.
2Adaptability or versatility
If applications manually create heterogeneous connections, then adaptability to different configurations is improved, but device complexity and error-proneness increase
Solution Approach 1:
The pool manager acts as an intermediary between applications and the heterogeneous connection pools. Applications interact with the pool manager through a unified interface, which handles the complexity of selecting and managing connections from different sub-pools. This mediator approach maintains adaptability while reducing application-side complexity.
3Adaptability or versatility
If applications bypass connection pools to create custom connections, then adaptability to specific configurations is improved, but resource usage efficiency deteriorates
Solution Approach 1:
The solution merges the advantages of connection pooling (resource efficiency) with the flexibility of custom connections. By combining multiple homogeneous sub-pools under a unified pool manager, the system achieves both resource reuse efficiency and configuration flexibility, eliminating the need for applications to bypass pools.
4Adaptability or versatility
If multiple separate connection pools are configured for different data stores, then adaptability to heterogeneous connections is improved, but handling complexity increases
Solution Approach 1:
The pool manager is designed with multi-functionality to handle multiple heterogeneous connection pools through a unified interface. It can dynamically select and manage connections from different sub-pools based on request requirements, reducing the complexity of managing multiple separate pools while maintaining support for diverse data stores.

AI summary
A connection handler is provided on a computing system. The connection handler provides an application with heterogeneous connection objects. Heterogeneous internal connection pools provide homogeneous connection objects related to a specific configuration. Requests are received from the application where the request includes an identification of a specifically configured connection object. A connection object is provided to the application from a respective internal connection pool.
