Differences between Snapshot Replication and Transactional Replication
Below are the differences between Snapshot Replication and Transactional Replication:
| Aspect | Snapshot Replication | Transactional Replication |
|---|---|---|
| Data Capture | Takes a point-in-time snapshot of the entire database | Captures and replicates individual transactions in real-time |
| Frequency of Updates | Typically used for less frequent updates | Used for more frequent updates, providing near real-time replication |
| Size of Data Transfer | Transfers the entire dataset during each replication cycle | Transfers only the changes made since the last replication cycle, reducing data transfer |
| Consistency | Provides a consistent snapshot of the database at a specific point in time | Maintains near real-time consistency between the publisher and subscribers |
| Use Cases | Suitable for reporting, backup, or distributing read-only copies of the database | Used for scenarios where near real-time data synchronization is required |
Types of Database Replication
Database replication is like making copies of your important documents so you have backups in case something happens to the original. There are different ways to make these copies, like having one main copy (master) that gets updated and then making copies (slaves) of that updated version. Another way is to have multiple main copies (masters) that can all be updated and share those updates. In this article, we will see different types of database replication.
