Core Components Introduction

1. Universal Integration Engine

The integration engine is the execution core of the entire cross-database synchronization system, implemented as a lightweight, independent Java program. Its main responsibilities include:

• Universal Schema Mapping: Mapping table structures between any database systems (e.g., PostgreSQL to MongoDB, Oracle to ClickHouse) and completing automatic schema creation
• Multi-Protocol Data Reading: Reading data from any source database through optimized concurrent methods, supporting various protocols and connection types
• Real-Time Change Capture: Reading incremental events from source databases through CDC mechanisms, log parsing, or polling methods depending on the database type
• Cross-Database Data Processing: Performing intelligent data transformations including type conversions, schema adaptations, field mappings, and custom processing logic
• Optimized Data Writing: Writing processed data to any target database using database-specific optimizations and batch processing strategies

In addition, the integration engine handles comprehensive operational tasks such as task monitoring, metric collection and reporting, intelligent error retry with exponential backoff, task progress persistence, checkpoint-based resumption, and real-time processing preview capabilities, ensuring smooth operation across any database combination.

The integration engine supports flexible deployment methods:

• Cloud-Hosted Deployment: Fully managed by XPipes in the cloud, users only need to ensure the engine can access their source and target databases, regardless of database types or locations.
• Private Network Independent Deployment: For enhanced security or compliance requirements, users can deploy the lightweight engine in their private network, maintaining exclusive control while supporting any database combination.
• Hybrid Deployment: Multiple engines can be deployed across different network zones, enabling complex integration scenarios across cloud and on-premises environments.

2. Task Manager

The task management module is responsible for building, scheduling, and managing the entire data synchronization task, mainly consisting of the following two parts:

• Web Frontend: Provides a user-friendly interface for users to create and manage data synchronization tasks
• Backend Module: Includes functions such as task building, task scheduling, metadata management, etc., providing comprehensive support for the frontend and computation engine

The backend module is in a key position in the product. It connects to users through the frontend to understand user intentions and presents data and task situations to users. It connects to the engine through a private protocol to dispatch tasks and scheduling, ensuring tasks run in a healthy state, and notifying users through notifications and emails when errors occur. All state persistence is also stored in a highly available database through the backend module, ensuring all configurations are not lost. Through the integration of the backend module, all components work together to form a complete user experience.

Similar to the engine, the backend module provides services through a single, independent Java process specifically designed for data services. It provides services in a position that users are not aware of. The backend module always runs in cloud service mode, and users do not need to deploy it locally.

3. State Storage

To ensure that user task configurations, various synchronization progresses, logs, metrics, alerts, user payment information, and other states are not lost, a reliable and fast database is needed to store them.

We chose MongoDB as the state database for storing all task configurations and running states. MongoDB's high performance and flexible data model make it efficient in managing a large amount of task information. MongoDB naturally supports replica sets and automatic failover, ensuring system stability and reliability.

4. Cloud Service Manager

The cloud service manager is responsible for managing user information, registration subscription information, and other key data. It ensures that each user's resources and permissions are reasonably allocated and managed, and rejects illegal requests. It also supports dynamic adjustment of subscription services, improving user experience.

The cloud service manager is separated from the task manager in logical code, but they work together as a single process at runtime to reduce the complexity of component deployment and maintenance.

5. Cloud Service Support Components

To ensure stable, reliable, and secure operation of cloud services, there are some other support components providing assistance, including:

1. K8s Management Group: Provides high availability services for all nodes except databases
2. K8s Computation Group: Provides deployment and dynamic scaling capabilities for cloud-hosted engines, ensuring the stability of data transmission nodes
3. WAF: Application firewall, used to prevent malicious request attacks and maintain service stability
4. Monitor: Service monitoring and alerting, inspecting the health status of processes, resource usage, core logic interfaces, as well as the operation status of CDN, domain names, certificates, and other services, ensuring that the R&D department can be notified promptly when services have anomalies
5. CI/CD Service: Provides compilation from code to artifacts, as well as online service update and rollback operations

Key Technology Choices

In addition to running components, XPipes has made the following considerations in key functional design:

1. Universal Pluggable Database Connectors

Each supported database system is implemented as a pluggable connector that is not pre-installed in the integration engine. When specific database connectors need to be used, the integration engine will dynamically download them from the platform, cache them locally for subsequent use, and automatically update them when new versions are available.

This design provides several significant benefits:

1. Lightweight Engine Deployment: By avoiding pre-installation of all database connectors, the integration engine remains lightweight and fast to deploy, regardless of how many database systems XPipes supports.
2. Instant Access to New Database Support: When new database connectors are released (e.g., support for a new NoSQL database or cloud service), users can immediately use them without upgrading their local integration engines.
3. Seamless Connector Updates: When features are added or bugs are fixed for existing database connectors, users automatically receive the improvements without any manual intervention, ensuring optimal performance across all database integrations.
4. Modular Architecture: Each database connector is independently developed, tested, and deployed, allowing for rapid innovation and specialized optimizations for different database systems.

With the universal pluggable connector design, XPipes can continuously expand database support and improve existing integrations, while users benefit from these enhancements immediately without any maintenance overhead.

2. Offline Operation Capability

The computation service has the ability to operate offline. When the computation service cannot connect to the task manager, it will continue to maintain the continuous operation of tasks, providing higher data accuracy assurance. There are many offline situations, such as:

1. User network interruption: The user's network environment loses access to the outside for some reason
2. XPipes network interruption: The cloud service provider has a failure and cannot communicate with the user's computation service
3. XPipes failure: The cloud service has a bug and cannot provide service
4. Intermediate communication anomaly: Network operator failure, communication quality deteriorates

When these problems occur, the local computation service will continue to synchronize data according to the existing task definition and progress, without interruption or error. However, due to communication interruption, monitoring information, logs, and synchronization breakpoints will temporarily be unable to be reported and persisted. After the network recovers, this information will be restored and reported.

The ability to operate offline greatly enhances the fault tolerance of the system, ensuring that the transmission of the data itself will not be affected under any extreme circumstances.

3. Multi-Cloud Database Service Integration

Rather than being tied to a single database technology, XPipes integrates with multiple cloud database services and supports on-premises deployments across all major database systems. This includes analytical databases like ClickHouse and Snowflake, transactional databases like PostgreSQL and MySQL, document databases like MongoDB, and specialized systems like Redis and Elasticsearch.

For cloud services, we leverage managed database offerings that provide automatic scaling, built-in high availability, and usage-based billing. This approach reduces operational overhead while ensuring optimal performance for each database type. For on-premises deployments, XPipes provides the same level of integration capabilities while respecting existing infrastructure investments.

Users can choose from several deployment options:

1. Managed Cloud Databases: Subscribe to various cloud database services directly through XPipes with integrated billing and management
2. Existing Cloud Subscriptions: Connect XPipes to your existing cloud database instances across any provider (AWS, Azure, GCP, etc.)
3. On-Premises Databases: Integrate with self-hosted database systems in private networks or hybrid environments
4. Mixed Environments: Combine cloud and on-premises databases in the same integration workflows

For managed services, XPipes provides additional operational support including monitoring, automated backups, and disaster recovery coordination. For self-managed databases, users maintain full control while benefiting from XPipes' universal integration capabilities.
