Dynamic reload duplication config #2102
Comments
@ninsmiracle There are several ways to update configs, http and remote_command, it's not a good idea to introduce another method. |
There are 2 key-value paris needed to be reload,such like this:
We only need to recognize these two parameters in this issues. |
Regarding the second discussion, I think update the config via http is not a good idea. In step1, we require the cluster maintenance personnel to push the config file to the nodes of the target cluster first. This step is to ensure that the latest config file can be read immediately when the cluster node is restarted after a downtime. In step2, we can see that we use So that, in step 3, you can use dup command without restart target cluster's nodes. |
Feature Request
In PR #2000 , we can ignore cluster id with paramater
dup_ignore_other_cluster_ids
.However, I think this function can be more flexible.
There is no doubt that, cluster id is very useful in multiple clusters duplication situation, backup-cluster can use it to judge data's priority.
So we may want to dynamic relod duplication config when we doing duplication.
Describe the feature you'd like:
Here is a case:
At beging, we have two clusters like cluster A dup data to cluster B. (A ----> B)
And now, demand changes:
C cluster also need to dup to cluster B. (A,C -----> B)
We don't need to restart the nodes on B, and can reload the config ABOUT DUP.
