Multi-Container Database Replication Testing Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current database replication systems require separate installations for primary and secondary systems, leading to increased costs and complexity in testing and implementing high availability and disaster recovery scenarios, especially in multi-container architectures.
Innovation Solution
A multi-container system architecture that allows for a single installation to simulate both primary and secondary systems within a single host, enabling efficient testing of database replication and recovery scenarios by generating a secondary tenant database to replicate information from a primary tenant database and replaying log information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate installations are used for primary and secondary database systems, then database replication and recovery can be tested, but system complexity and testing costs increase
Solution Approach 1:
The patent merges the primary and secondary database systems into a single containerized environment where both database instances share the same host system. This consolidation allows replication and recovery testing without requiring separate physical installations, directly reducing system complexity while maintaining reliable replication capabilities through the shared container architecture
Solution Approach 2:
The patent creates a copy of the primary database system within a separate container to serve as the secondary database. This virtual copy enables replication and recovery scenario testing without needing a completely separate physical installation, thereby reducing complexity while preserving the ability to test high availability and disaster recovery functions
2Reliability
If separate installations are used for primary and secondary systems, then replication testing is possible, but testing costs increase
Solution Approach 1:
By combining both primary and secondary database systems into a single host with containerization, the patent eliminates the need for duplicate hardware infrastructure. This merging approach reduces testing implementation costs while maintaining the ability to test disaster recovery scenarios through the shared resource environment
Solution Approach 2:
The containerized platform provides multi-functionality by allowing the same host system to run both primary and secondary database instances simultaneously. This universal setup enables a single installation to serve multiple testing purposes including replication, high availability, and disaster recovery scenarios, thereby reducing overall testing costs

AI summary
Testing a database replication system within a multi-container system architecture comprises receiving a first request for creating a database recovery system within a multi-container system architecture. The multi-container system architecture is configured to contain a plurality of tenant databases and a system database, and the database recovery system includes a primary system and a secondary system. The primary system is then identified from the information in the first request. Upon identification, a first tenant database included in the plurality of tenant databases is determined that corresponds to the identified primary system. Upon determining the first tenant database, a second tenant database of the plurality of tenant database is generated that corresponds to the secondary system, and which is enabled to test replicating information that would otherwise be associated with the first tenant database.
