Automatic Transaction Retry:
YottaDB’s TSTART, TCOMMIT, and TROLLBACK with automatic conflict handling (including forced retries) make it more resilient, especially in environments with high transaction volume or contention.
Internal Retry Logic: Developers don’t have to write retry logic for transaction collisions. YottaDB's engine automatically handles conflict detection, rollback, and retry, reducing the burden on the application code.
Pathological Conflict Handling:
In more extreme cases, where persistent conflicts occur (like deadlocks in other systems), YottaDB forces a resolution, ensuring that the system doesn’t hang or collapse under heavy contention. This is a crucial safety net that most databases don’t provide out of the box.
Simplified Error Handling:
YottaDB’s automatic error handling and retry mechanism simplify the process of building resilient applications. Developers only need to be aware of catastrophic failures, while the system internally handles most conflict-related errors.
PostgreSQL/MySQL:
These databases allow for manual
handling of transaction conflicts via APIs like SAVEPOINT
or by catching errors, but do not retry transactions automatically.
If there’s a conflict or deadlock, the application needs to retry
manually.
Example: If a transaction fails due to a conflict, you’d need to check for the error and manually retry the operation, which is error-prone and difficult to handle efficiently at scale.
MongoDB:
MongoDB uses optimistic
concurrency control, meaning applications need to detect and handle
conflicts themselves. It provides the WriteConcern and
retry logic at the application level, but this is again manual and
not as seamless as YottaDB’s automatic rollback and retry.
Oracle/SQL Server:
Pessimistic locking helps prevent many conflicts, but deadlocks are still common, and the database typically just kills one transaction, leaving the application to retry it manually.
Most databases do not force one transaction to proceed when conflicts persist—they rely on the application to detect and handle these cases.
Built-in Resilience: The automatic handling of transaction retries, even under persistent conflicts, makes YottaDB highly resilient without needing complex application-level logic.
Developer Simplicity: Developers don’t need to write or maintain extensive error-handling and retry logic. The database handles most of the work behind the scenes, leading to cleaner code and fewer bugs related to transaction management.
Safety in Production: In high-concurrency or production environments, where transaction conflicts are more common, YottaDB’s automatic retry and conflict resolution system provides a level of reliability that is often missing in other databases.
YottaDB’s automatic transaction conflict resolution and retry features are not common among other databases, where developers are typically expected to handle such issues manually. This is a big advantage in terms of robustness and ease of development, especially in scenarios where transaction conflicts are likely, as in high-concurrency or load-heavy applications. It allows YottaDB to remain resilient and efficient, minimizing downtime or manual intervention due to conflicts, while most other databases require explicit coding for these situations, increasing the risk of failure during load testing or production runs.

"i'm suprised ydb doesn't highlight this as one of its strong selling points. it's unique and essential to be rock solid."
-------------------------------------
You're absolutely right—it’s surprising that YottaDB (YDB) doesn’t emphasize the automatic transaction conflict resolution and retry mechanism more prominently as a key selling point. This feature provides a high level of robustness and resilience that sets YDB apart from many other databases.
Here are a few reasons why this capability should be front and center in their messaging:
Robustness and Reliability:
YDB’s ability to automatically handle transaction conflicts, rollback, and retry without developer intervention ensures high reliability in production environments, especially under high concurrency.
Other databases require developers to manage this complexity, which introduces potential points of failure, whereas YDB does this transparently and efficiently.
Simplified Development:
Developers using YDB don’t need to write or maintain complicated transaction management and retry logic, which reduces development time and complexity. This also helps avoid common pitfalls like unhandled deadlocks or conflicts.
In scenarios where failure cases are common (e.g., heavy writes, concurrent updates), YDB’s internal handling of conflicts keeps applications simpler and more focused on business logic rather than error handling.
Automatic Conflict Resolution:
The system’s ability to handle even persistent conflicts, where one transaction is forced to proceed while others wait, ensures that applications never get stuck. This capability is vital for maintaining uptime and preventing deadlocks from cascading into broader failures.
Load Testing and High-Concurrency Readiness:
As you mentioned, most databases perform fine until load testing or real-world concurrency issues expose weak points in error handling and transaction management. YDB’s built-in resilience makes it particularly suited for high-concurrency applications where transactional integrity is critical.
Specialized Audience:
YDB is primarily targeted at organizations familiar with MUMPS, especially in healthcare (like VistA). These users may take the transaction-handling feature for granted since it’s a natural part of how MUMPS operates.
However, in broader enterprise or startup environments, where developers work with databases like PostgreSQL, MySQL, or NoSQL systems, YDB’s automatic transaction resolution would be considered a significant advantage—if they knew about it.
Focus on Scalability and Flexibility:
YDB tends to highlight its scalability, flexibility, and atomic data store features, which are also essential, but its transaction conflict resolution is a more subtle, technical advantage that doesn't always get the spotlight.
Legacy Perception:
Because YDB has its roots in MUMPS, some may see it as a legacy technology, despite its modern capabilities. Highlighting features like automatic transaction management could help dispel this perception and attract developers looking for reliable, modern databases with robust internal mechanics.
To make the most of this feature, YottaDB could:
Promote Real-World Use Cases: Showcase how this conflict resolution system ensures seamless operation in high-transaction, high-concurrency scenarios (e.g., financial systems, healthcare, IoT), where other databases might struggle.
Highlight Developer Simplicity: Emphasize that developers don’t have to worry about complex transaction handling code, which saves time, reduces bugs, and makes applications more robust out of the box.
Stress Load-Test Readiness: Show that YDB is ready to handle real-world transaction volumes without needing a complex layer of error handling, retry logic, or manual conflict management.
Provide Comparative Examples: Demonstrate how YDB’s automatic conflict resolution stacks up against common databases where such logic needs to be written manually.
YDB’s automatic handling of transaction conflicts and retries is a hidden gem that should be a key differentiator. It’s an essential feature that not only makes the database rock-solid but also simplifies development and improves performance in demanding environments. Promoting this more heavily could help YDB stand out, especially in competitive markets where developers are often left to handle these challenges themselves with other databases.
