A cluster is an independant service type.
- This simplifies the configurations (ties to service_type)
- The guest impl can be different for each service_type
- We don't need cluster type and service_type when defining a cluster
Think: A instance is an instance is a cluster is an instance is *NOT* replication
Definition of cluster for purposes of Trove:
A cluster must provide
- High Availablility
- Fault Tolerance
A cluster object is represented as an instance with a metadata attribute
containing node information. A node is a sub-resource of a cluster and
has a limited number of actions that can be performed on them.
Create cluster:
Create a cluster with flavor X and size Y. All nodes are of equal size.
POST /instance
{
"name": "foobar",
"flavor": "{flavor_id}",
"service_type": "{service_type_id}",
"size": 50,
"metadata": {
"nodes": 5,
}
}
Downsize a cluster (Delete nodes):
PATCH /instance/{id}
{
"metadata" {
"nodes": 3
}
}
Initialize a node:
This only where applicable...
PATCH /instance/{id}/node/{id}/initialize
We think of replication as a capability of some service types. Not every
service type will have this capability and it should be configurable via
the service types capabilities feature.
What you cannot do:
- create a master and slave in one call
- one call per action means simplified workflow
POST /instance
{
"name": "foobar",
"flavor": "flavor_id",
"service_type": "mysql-5.1",
"size": 50,
"metadata": {
"replication_type": "replication_type_id",
"replication_data": {
"master_instance": "instance_uuid"
}
}
}
