This behavior is only useful with backup software that independently

By default, or when this parameter is true, pg_backup_stop will
wait for WAL to be archived when archiving is enabled. On a

useful to run pg_switch_wal on the primary in order to trigger

example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains
is set to 5 and pods with the same labelSelector spread as
2/2/2: | zone1 | zone2 | zone3 | | P P | P P | P P |
The number of domains is less than 5(MinDomains), so \"global
minimum\" is treated as 0. In this situation, new pod with
the same labelSelector cannot be scheduled, because computed
skew will be 3(3 - 0) if new Pod is scheduled to any of the
three zones, it will violate MaxSkew. \n This is a beta field
and requires the MinDomainsInPodTopologySpread feature gate
to be enabled (enabled by default)."

nodeAffinityPolicy:
description: "NodeAffinityPolicy indicates how we will treat

NodeInclusionPolicyInPodTopologySpread feature flag."

topologyKey:
description: TopologyKey is the key of node labels. Nodes that
have a label with this key and identical values are considered
to be in the same topology. We consider each <key, value>
as a "bucket", and try to put balanced number of pods into
each bucket. We define a domain as a particular instance of
a topology. Also, we define an eligible domain as a domain
whose nodes meet the requirements of nodeAffinityPolicy and
nodeTaintsPolicy. e.g. If TopologyKey is "kubernetes.io/hostname",
each Node is a domain of that topology. And, if TopologyKey
is "topology.kubernetes.io/zone", each zone is a domain of
that topology. It's a required field.

whenUnsatisfiable:
description: 'WhenUnsatisfiable indicates how to deal with a
pod if it doesn''t satisfy the spread constraint. - DoNotSchedule
(default) tells the scheduler not to schedule it. - ScheduleAnyway
tells the scheduler to schedule the pod in any location, but
giving higher precedence to topologies that would help reduce
the skew. A constraint is considered "Unsatisfiable" for an
incoming pod if and only if every possible node assignment
for that pod would violate "MaxSkew" on some topology. For
example, in a 3-zone cluster, MaxSkew is set to 1, and pods
with the same labelSelector spread as 3/1/1: | zone1 | zone2
| zone3 | | P P P | P | P | If WhenUnsatisfiable is
set to DoNotSchedule, incoming pod can only be scheduled to
zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on
zone2(zone3) satisfies MaxSkew(1). In other words, the cluster
can still be imbalanced, but scheduler won''t make it *more*
imbalanced. It''s a required field.'

dataSourceRef allows any non-core object, as well as PersistentVolumeClaim

maxSkew:
description: 'MaxSkew describes the degree to which
pods may be unevenly distributed. When `whenUnsatisfiable=DoNotSchedule`,
it is the maximum permitted difference between the
number of matching pods in the target topology and
the global minimum. The global minimum is the minimum
number of matching pods in an eligible domain or zero
if the number of eligible domains is less than MinDomains.
For example, in a 3-zone cluster, MaxSkew is set to
1, and pods with the same labelSelector spread as
2/2/1: In this case, the global minimum is 1. | zone1
| zone2 | zone3 | | P P | P P | P | - if MaxSkew
is 1, incoming pod can only be scheduled to zone3
to become 2/2/2; scheduling it onto zone1(zone2) would
make the ActualSkew(3-1) on zone1(zone2) violate MaxSkew(1).
- if MaxSkew is 2, incoming pod can be scheduled onto
any zone. When `whenUnsatisfiable=ScheduleAnyway`,

minDomains:
description: "MinDomains indicates a minimum number
of eligible domains. When the number of eligible domains
with matching topology keys is less than minDomains,
Pod Topology Spread treats \"global minimum\" as 0,
and then the calculation of Skew is performed. And
when the number of eligible domains with matching
topology keys equals or greater than minDomains, this
value has no effect on scheduling. As a result, when
the number of eligible domains is less than minDomains,
scheduler won't schedule more than maxSkew Pods to
those domains. If value is nil, the constraint behaves
as if MinDomains is equal to 1. Valid values are integers
greater than 0. When value is not nil, WhenUnsatisfiable
must be DoNotSchedule. \n For example, in a 3-zone
cluster, MaxSkew is set to 2, MinDomains is set to
5 and pods with the same labelSelector spread as 2/2/2:
| zone1 | zone2 | zone3 | | P P | P P | P P |
The number of domains is less than 5(MinDomains),
so \"global minimum\" is treated as 0. In this situation,
new pod with the same labelSelector cannot be scheduled,
because computed skew will be 3(3 - 0) if new Pod
is scheduled to any of the three zones, it will violate
MaxSkew. \n This is a beta field and requires the

topologyKey:
description: TopologyKey is the key of node labels.
Nodes that have a label with this key and identical
values are considered to be in the same topology.
We consider each <key, value> as a "bucket", and try
to put balanced number of pods into each bucket. We
define a domain as a particular instance of a topology.
Also, we define an eligible domain as a domain whose
nodes meet the requirements of nodeAffinityPolicy
and nodeTaintsPolicy. e.g. If TopologyKey is "kubernetes.io/hostname",
each Node is a domain of that topology. And, if TopologyKey
is "topology.kubernetes.io/zone", each zone is a domain
of that topology. It's a required field.

precedence to topologies that would help reduce the
skew. A constraint is considered "Unsatisfiable" for
an incoming pod if and only if every possible node
assignment for that pod would violate "MaxSkew" on
some topology. For example, in a 3-zone cluster, MaxSkew
is set to 1, and pods with the same labelSelector
spread as 3/1/1: | zone1 | zone2 | zone3 | | P P P
| P | P | If WhenUnsatisfiable is set to DoNotSchedule,
incoming pod can only be scheduled to zone2(zone3)
to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3)
satisfies MaxSkew(1). In other words, the cluster

volume binding will only succeed if the

they must have the same value. For backwards
compatibility, when namespace isn''t specified

* While dataSource only allows two specific

any non-core object, as well as PersistentVolumeClaim

preserves all values, and generates an
