The cluster is currently being created, and may be destroyed
if the creation process encounters an error.
A cluster may not be able to serve requests while being created.
The cluster has no backing nodes. The data (tables) still
exist, but no operations can be performed on the cluster.
The state of the cluster could not be determined.
The cluster has been successfully created and is ready to serve requests.
The cluster is currently being resized, and may revert to its previous
node count if the process encounters an error.
A cluster is still capable of serving requests while being resized,
but may exhibit performance as if its number of allocated nodes is
between the starting and requested states.
