Which type of replication is typically faster in delivering immediate updates?

Synchronous replication is typically faster in delivering immediate updates because it ensures that data is written to both the primary and secondary storage locations at the same time. This means that once an operation is completed on the primary site, that operation is instantly reflected on the secondary site, creating a consistent and up-to-date view of the data across both locations.

Consequently, applications or services relying on this data can operate with real-time accuracy, making it ideal for environments where immediate data consistency is critical, such as financial transactions or real-time data processing. This immediate update capability is a defining characteristic of synchronous replication, as it guarantees that both sites have the same data at any given moment, thereby minimizing the risk of data discrepancies.

In contrast, other replication types do not offer this same level of immediacy; for instance, asynchronous replication involves a delay, as data is sent to the secondary site after it has been written to the primary, potentially leading to moments where the data may not be in sync. Thus, synchronous replication stands out for its ability to provide immediate updates effectively.
