Returns properties of provisioned clusters including general cluster properties, cluster database properties, maintenance and backup properties, and security and access properties. This operation supports pagination. For more information about managing clusters, go to Amazon Redshift Clusters in the Amazon Redshift Cluster Management Guide .
If you specify both tag keys and tag values in the same request, Amazon
Redshift returns all clusters that match any combination of the specified
keys and values. For example, if you have owner
and environment
for tag keys,
and admin
and test
for tag values, all clusters that have any combination of
those values are returned.
If both tag keys and values are omitted from the request, clusters are returned regardless of whether they have tag keys or values associated with them.

Request lenses
dcClusterIdentifier :: Lens' DescribeClusters (Maybe Text) Source
The unique identifier of a cluster whose properties you are requesting. This parameter is case sensitive.
The default is that all clusters defined for an account are returned.
dcMarker :: Lens' DescribeClusters (Maybe Text) Source
An optional parameter that specifies the starting point to return a set of
response records. When the results of a DescribeClusters
request exceed the
value specified in MaxRecords
, AWS returns a value in the Marker
field of the
response. You can retrieve the next set of response records by providing the
returned marker value in the Marker
parameter and retrying the request.
Constraints: You can specify either the ClusterIdentifier parameter or the Marker parameter, but not both.
dcMaxRecords :: Lens' DescribeClusters (Maybe Int) Source
The maximum number of response records to return in each call. If the number
of remaining response records exceeds the specified MaxRecords
value, a value
is returned in a marker
field of the response. You can retrieve the next set
of records by retrying the command with the returned marker value.
Default: '100'
Constraints: minimum 20, maximum 100.
dcTagKeys :: Lens' DescribeClusters [Text] Source
A tag key or keys for which you want to return all matching clusters that are
associated with the specified key or keys. For example, suppose that you have
clusters that are tagged with keys called owner
and environment
. If you
specify both of these tag keys in the request, Amazon Redshift returns a
response with the clusters that have either or both of these tag keys
associated with them.
dcTagValues :: Lens' DescribeClusters [Text] Source
A tag value or values for which you want to return all matching clusters that
are associated with the specified tag value or values. For example, suppose
that you have clusters that are tagged with values called admin
and test
. If
you specify both of these tag values in the request, Amazon Redshift returns
a response with the clusters that have either or both of these tag values
associated with them.

Response lenses
dcrClusters :: Lens' DescribeClustersResponse [Cluster] Source
A list of Cluster
objects, where each object describes one cluster.
dcrMarker :: Lens' DescribeClustersResponse (Maybe Text) Source
A value that indicates the starting point for the next set of response
records in a subsequent request. If a value is returned in a response, you
can retrieve the next set of records by providing this returned marker value
in the Marker
parameter and retrying the command. If the Marker
field is
empty, all response records have been retrieved for the request.
