Create and Deploy Replication Nodes
The final step in your configuration process is to create replication nodes on
every Storage Node in your data store. You do this using the topology
create
and plan deploy-topology
commands. The topology
create
command takes the following arguments:
-
topology name - A string to identify the topology.
-
pool name - A string to identify the pool.
-
number of partitions
The initial configuration is based on the number of Storage Nodes specified by the pool. This number is fixed once the topology is created and it cannot be changed. The command will automatically create an appropriate number of shards and replication nodes based upon the Storage Nodes in the pool.
(Total number of disks hosted by the Storage Nodes /
Replication Factor) * 10
To get a more accurate estimate for production use, see Number of Partitions.
The plan deploy-topology
command requires a topology name.
Once you issue the following commands, your data store is fully installed and configured:
kv-> topology create -name topo -pool BostonPool -partitions 300
Created: topo
kv-> plan deploy-topology -name topo -wait
Executed plan 6, waiting for completion...
Plan 6 ended successfully
Note:
If you have not created an explicit Storage pool , use-pool AllStorageNodes
in the above command.
As a final sanity check, you can confirm that all of the plans succeeded using the show plans
command:
kv-> show plans
1 Deploy Zone (1) SUCCEEDED
2 Deploy Storage Node (2) SUCCEEDED
3 Deploy Admin Service (3) SUCCEEDED
4 Deploy-RepNodes (4) SUCCEEDED
You can then exit the command line interface.
kv-> exit
