Database Consistence Modes
Table of Contents
In a database, data consistency refers to the accuracy and integrity of data. It is important to maintain data consistency in order to ensure that the data in the database is correct and reliable. There are several different models for maintaining data consistency in a database, including the following:
# Database Consistence Modes
Strong consistency: This model ensures that all transactions see the latest version of data, and that all transactions are executed in the order that they were committed. This model provides the highest level of data consistency, but can also have the highest overhead and latency.
Eventual consistency: This model allows transactions to be executed out of order, and ensures that all transactions eventually see the latest version of data. This model provides lower levels of data consistency, but can have lower overhead and latency.
Linearizability: This model ensures that all transactions are executed in the order that they were committed, and that all transactions see the latest version of data. This model provides a balance between strong consistency and eventual consistency, and is often used in distributed systems.
Read your own writes: This model ensures that a transaction can read its own writes, but does not guarantee that other transactions can see the updates. This model is often used in systems with high write workloads.
Monotonic reads: This model ensures that a transaction can only read data that is at least as up-to-date as the data that it has already read. This model is often used in systems with high read workloads.
Overall, there are several different models for maintaining data consistency in a database, and the appropriate model will depend on the specific requirements and constraints of the application. By understanding the trade-offs and limitations of each model, you can choose the model that best meets the needs of your application.
