Can geo replication be synchronous?

The default replication type in active geo-replication is asynchronous. However, if the application needs to have synchronous replication, then you can do so by calling sp_wait_for_database_copy_sync immediately after committing a transaction.

What are the types of storage replication?

The answer is Locally Redundant Storage. Storage replication data is not replicated across multiple datacenters in Locally Redundant Storage (LRS) type of storage. Three copies of the data are maintained in a LRS. A key aspect worth noting is that the LRS replication cost option is the least expensive and durable.

What is geo redundancy?

  4. Navigate to Geo-Replication blade. …
  5. Navigate to the Create Secondary blade.

What is difference between synchronous and asynchronous replication?

Most synchronous replication products write data to primary storage and the replica simultaneously. As such, the primary copy and the replica should always remain synchronized. In contrast, asynchronous replication products copy the data to the replica after the data is already written to the primary storage.

What does synchronous replication mean?

Synchronous replication is the process of copying data over a storage area network, local area network or wide area network so there are multiple, up-to-date copies of the data.

What is the difference between synchronous and asynchronous?

Synchronous = happens at the same time. Asynchronous = doesn’t happen at the same time. With synchronous learning, participants can receive immediate feedback. With asynchronous learning, the participants can learn at their own pace.
