When managing database migrations via LuaSQL, there is a discrepancy in how Data Definition Language (DDL) statements interact with transaction boundaries compared to Data Manipulation Language (DML) statements. In many database drivers, executing a schema change—such as CREATE TABLE or ALTER TABLE —triggers an implicit commit. This behavior potentially bypa
Transactional Isolation and Example Retries Maintaining test isolation typically involves wrapping RSpec examples in database transactions using around(:each) hooks or integration tools like DatabaseCleaner. This ensures that writes are rolled back after each example to prevent state leakage. When integrating external retry mechanisms—such as the rspec-retry
Transactional DDL Behavior Laminas-Db utilizes a Connection interface to manage transactions via beginTransaction() , commit() , and rollback() . These methods act as wrappers for the underlying PDO driver. However, many relational database engines, such as MySQL, trigger an implicit commit when Data Definition Language (DDL) statements are executed, which p
When integrating external API triggers with ProcessWire page updates, there is a risk of duplicate data entries if a network timeout occurs after a write operation but before the confirmation is received. While ProcessWire utilizes PDO for database interactions, the framework does not natively provide idempotency keys or a built-in mechanism to deduplicate r
The goal is to guarantee exactly‑once writes when a PostgreSQL deadlock forces a transaction to abort in an AdonisJS service. AdonisJS provides a retries option on Database.transaction that automatically re‑executes the callback, but the documentation notes that writes flushed before the error may already be committed, risking duplicate rows unless the opera
