Data Center Replication for GridGain 9 Clusters
Control Center supports data replication between clusters. You can configure it using the CLI or directly via the Data Center Replication screen in Control Center.
Data Replication Screen
The Data Replication screen lets you configure and manage replication between clusters.

By default, the list of existing replications includes the following columns:
Column | Description |
---|---|
Replication name |
Unique replication name. |
Target name |
The name of the target cluster. |
Worker node |
Name of the worker node. |
Replication state |
State of the selected replication. Possible states are:
For |
Source name |
The name of the source cluster. |
Errors |
Table errors if any occurred. |
FST progress |
Full state transfer progress, if initiated. |
To check the status of individual tables or nodes, click on the Replication name of the specific replication. A panel with two tabs will appear on the right side of the screen.
Tables Tab:

Nodes Tab:

Filters
Use the Filters panel to search and filter replications by name, cluster or specific tables.

Creating Data Replication
To create a replication, start by specifying the source cluster and one or more source node addresses within that cluster. Then select the target cluster and its nodes.

Selecting Tables For Replication
After creating the replication, select all the tables you want to replicate.

Once the setup and validation are complete, the status will change to Replicating
.
Managing Replications
You can stop replication for all tables or select individual tables to pause. Optionally, you can specify a flush point to perform replication up to a certain timestamp. The flush point guarantees that all data up to that timestamp is fully replicated, regardless of whether it is in the past or future.

To remove a replication, click Remove from the ⋮ menu for the selected replication. The dialog will show all tables that will stop replicating.

To remove multiple replications at once, select the checkboxes next to the replications you want to delete, then open the ⋮ menu and click Remove. In this case, the dialog will list the names of the selected replications instead of showing tables.
