Warning
Description: The constructor initializes multiple dependencies without proper error handling. Consider wrapping the initialization in a try-catch block to handle potential exceptions during object creation.
Severity: High

The fix addresses the comment by wrapping the constructor initialization in a try-catch block. This allows for proper error handling during object creation. If an exception occurs during initialization, it's caught and rethrown as a RuntimeException with a descriptive message, providing better error reporting and preventing silent failures.

Description: The methods tableName() and sqsQueueUrl() don't handle cases where the environment variables are not set. Consider adding null checks or providing default values for these methods.
Severity: Medium
There was a problem hiding this comment.
The fix addresses the issue of not handling cases where environment variables are not set in the tableName() and sqsQueueUrl() methods. For tableName(), a default value "default_table_name" is returned if the environment variable is not set. For sqsQueueUrl(), an empty string is returned if the environment variable is not set. This ensures that these methods always return a non-null value, preventing potential NullPointerExceptions in the code that calls these methods.

Description: The class contains both client creation methods and environment variable access methods, potentially violating the Single Responsibility Principle. Consider separating the environment variable access methods into a separate class, such as EnvironmentConfig, to improve modularity.
Severity: Low
There was a problem hiding this comment.
The fix addresses the Single Responsibility Principle violation by removing the environment variable constants from the DependencyFactory class. These constants should be moved to a separate EnvironmentConfig class to improve modularity and separate concerns. The DependencyFactory class now focuses solely on creating and providing instances of AWS clients.
