Add Versioning to Sequelize Model for Optimistic Concurrency Control

[pushoo-sharma]

Recommendation

Add Versioning to Sequelize Model

1. Model Modification:

   • Include a version field in the Count model to track the version of each record.

2. Update Logic:

   • Modify the update logic to include the current version in update queries, ensuring optimistic concurrency control.

Expected Benefits

1. Conflict Prevention:

   • Versioning helps prevent conflicts when multiple updates are attempted concurrently by ensuring that updates are only applied if the version matches the expected value.

2. Optimistic Concurrency Control:

   • Optimistic concurrency control allows for better performance by avoiding exclusive locks during reads, allowing multiple transactions to proceed concurrently and resolving conflicts at the time of update.

3. Data Consistency:

   • With versioning, updates are performed in a controlled manner, maintaining data consistency and integrity.

Usage Guidelines

1. Include Version in Update Queries:

   • Developers should be aware of the need to include the current version in update queries to ensure successful updates.

2. Documentation Update:

   • Update the documentation to reflect the changes made to the model and provide guidelines on how to work with versioning.

Expected Outcome

The addition of versioning to the Sequelize model will enhance the application's ability to handle concurrent updates more effectively, preventing conflicts and ensuring data consistency.
