Bemi - Key Features and Functionality
Bemi Overview
Bemi is an AI-driven tool that specializes in providing an automatic, reliable audit trail for PostgreSQL databases, ensuring data integrity and compliance. Here are the key features and how they work:Automatic Audit Trail
Bemi implements a Change Data Capture (CDC) design pattern by connecting to the built-in replication log of a PostgreSQL database. This allows it to ingest all changes at the database level and store them in a structured format in a separate, serverless PostgreSQL database. This feature ensures that all data changes, including those made directly via SQL queries, are captured with 100% accuracy.Seamless Setup and Integration
Bemi connects to your PostgreSQL database in a read-only mode, which means it does not require write permissions. This setup can be completed in just a few minutes, and it integrates seamlessly with existing tools and codebases, including popular Object-Relational Mappers (ORMs) like Prisma and TypeORM.Contextualized Data
Bemi enhances low-level database changes by stitching them with application-specific context. This includes information about who made the change, where the change was made (e.g., API endpoint, worker), and how the change was made. This contextual data is stored in a structured format, allowing for easy querying and analysis of historical records.Security and Data Protection
Bemi prioritizes security with encryption for data both at rest and in transit. It uses TLS encryption and connection poolers to ensure secure data transfer. The data is stored in an auto-scaled and optimized serverless PostgreSQL database, further enhancing security and scalability.Proactive Troubleshooting
Bemi’s AI capabilities provide clear visibility into sensitive data changes, enabling proactive troubleshooting. Users can easily identify and address potential issues before they become compliance concerns, reducing downtime and ensuring data integrity.Regulatory Compliance
Bemi facilitates easy compliance with software compliance requirements by providing a comprehensive audit log. This log can be used for audit, digital forensics, and troubleshooting purposes, helping businesses meet regulatory standards effectively.Scalability and Flexibility
Bemi is designed to handle large data volumes and scales automatically. It supports various hosting partners and offers different plans to accommodate various data change volumes, from 1,000 new data changes per month to custom plans for larger needs.User Interface and Support
Bemi features an intuitive interface that makes it easy for users to manage and analyze data changes. It also offers standard and priority support options, along with dedicated Slack channels for assistance. The tool supports selective table tracking and column-based filter rules, providing users with granular control over what data changes are tracked.AI Integration
While Bemi is not explicitly described as using AI for complex analytics, it leverages AI capabilities to provide clear visibility into sensitive data changes and to enhance the contextual information associated with these changes. This makes it easier for users to navigate through the narrative of modifications made, facilitating proactive troubleshooting and compliance management.Conclusion
In summary, Bemi offers a comprehensive solution for tracking database changes, ensuring data integrity, and facilitating regulatory compliance, all through a seamless, secure, and scalable approach. Bemi - Performance and Accuracy
Performance
Bemi is built to track database changes with high performance and reliability. Here are some highlights:- Bemi uses PostgreSQL’s Write-Ahead Log (WAL) and implements Change Data Capture (CDC), ensuring 100% reliability in tracking database changes.
- It operates in the background without affecting runtime execution, which means it does not slow down your database operations.
- The system is designed for high performance, allowing for real-time tracking of database changes without impacting the database’s overall performance.
Accuracy
The accuracy of Bemi is a significant strength:- By leveraging the WAL and CDC, Bemi ensures that all database changes are captured accurately and comprehensively.
- It provides the ability to time travel through changes and easily filter them, which enhances the accuracy of tracking and auditing database modifications.
- The integration at both the database and application levels allows for adding application-specific context to the changes, making the data more meaningful and accurate.
Limitations and Areas for Improvement
While Bemi offers strong performance and accuracy, there are a few areas to consider:- Integration Requirements: Bemi requires integration at the database level, which might be a barrier for some users who are not familiar with PostgreSQL’s WAL and CDC mechanisms. However, this is a necessary step for its functionality.
- Application-Level Integration: While integrating at the application level is recommended for adding context, it may require additional setup and configuration. This could be a learning curve for some users, especially if they are using different Object-Relational Mappers (ORMs).
- Scalability and Support: While Bemi includes features like worker ingesters, queues for fault tolerance, and an automatically scalable cloud-hosted PostgreSQL, the scalability and support needs of very large or highly distributed databases would need to be carefully evaluated.

What does Bemi do?
Bemi is a tool that provides an automatic audit trail for PostgreSQL databases. It tracks data changes reliably without requiring complex engineering or costly infrastructure. Bemi connects to your PostgreSQL database (read-only) and captures data changes, storing them in a separate, auto-scaled serverless PostgreSQL database.How does Bemi connect to a database?
Bemi connects to a database using a design pattern called Change Data Capture (CDC). It links to the built-in replication log of the PostgreSQL database, ingesting all changes at the database level and storing them in a structured format in a destination database. This connection can be securely configured through the Bemi dashboard UI in a few seconds.What data does Bemi store and how can it be used?
Bemi stores low-level database changes and stitches them with application-specific context, such as who made the change, where it was made (e.g., API endpoint, worker), and how it was made. This information is stored in a structured format, allowing for time travel queries to fetch historical records, group changes by user or API request, and revert changes if necessary.How secure is the data and where is it stored?
Bemi prioritizes data security by storing all data in an auto-scaled and optimized serverless PostgreSQL database. The data is encrypted both at rest and in transit, and Bemi offers a fully managed, secured cloud solution that includes dedicated Bemi worker ingesters, queues for fault tolerance, and enhanced UI features. Users can also choose to store data in any destination database, including the original one.Is Bemi similar to ETL tools and warehouse solutions?
Bemi is different from ETL tools and data warehousing solutions. While it uses similar techniques to capture data changes, Bemi focuses specifically on change data capture and does not perform transformations or loading into different data warehouses. It integrates not just on the database level but also on the application level, enhancing data changes with context such as who and where the changes were made.Is Bemi like Git for data and does it implement Event Sourcing?
Bemi allows for event-sourcing any database without requiring significant changes to existing code or switching to specialized databases.
