[SOLVED] Replication logic works.

Replication logic works.

Interested in how replication will work on a large number of nodes.
For example, we have 20 nodes. each node runs 6vm
Option 1. Replication is configured that vm with 1 and 2 nodes among themselves, 3 and 4 nodes among themselves, and so on, that is, 10 pairs of nodes. Tell me, synchronization on each pair of nodes will work independently or replication on nodes 3 and 4 will wait until replication on nodes 1 and 2 ends.

Option 2. Replication is configured 1 and 2 nodes to 3 nodes, 3 and 4 nodes to 5 nodes. As in that case there will be a sequence of replication.

Hi,

• A replication job is defined for a single guest with a single target.
• When a guest moves to the replication target, the source becomes the new target.
• Each node will execute the replication jobs for the guests that are currently on it.
• Jobs are executed according to the replication schedule, but each node executes at most one job at a given time, the rest are queued.
• There is nothing preventing multiple nodes from running replication at the same time.
