Availability zones, and their associated data distribution policy, are generally created using node deploy configuration (see the section called “AvailabilityZone”). There is also a default availability zone and data distribution policy automatically defined that can be used if the default characteristics are adequate. The names of the defaults are:
default-cluster-wide-availability-zone -
availability zone
default-dynamic-data-distribution-policy -
data distribution policy
The default availability zone has these characteristics:
includes all nodes in the cluster.
node membership is elastic as nodes are added and removed from the cluster.
disables quorum management.
uses the default data distribution policy.
The default data distribution policy has these characteristics:
is a dynamic data distribution policy.
uses distributed consistent hashing for data partitioning.
uses synchronous replication.
has a replication count of two.
