	// DeprecatedPolicySpec enable the use of deprecated policy spec
	DeprecatedPolicySpec featuregate.Feature = "DeprecatedPolicySpec"
	// LegacyObjectTypeIdentifier enable the use of legacy object type identifier for selecting ref-object
	LegacyObjectTypeIdentifier featuregate.Feature = "LegacyObjectTypeIdentifier"
	// DeprecatedObjectLabelSelector enable the use of deprecated object label selector for selecting ref-object
	DeprecatedObjectLabelSelector featuregate.Feature = "DeprecatedObjectLabelSelector"
	// LegacyResourceTrackerGC enable the gc of legacy resource tracker in managed clusters
	LegacyResourceTrackerGC featuregate.Feature = "LegacyResourceTrackerGC"
	// LegacyComponentRevision if enabled, create component revision even no rollout trait attached
	LegacyComponentRevision featuregate.Feature = "LegacyComponentRevision"
	// LegacyResourceOwnerValidation if enabled, the resource dispatch will allow existing resource not to have owner
	// application and the current application will take over it
	LegacyResourceOwnerValidation featuregate.Feature = "LegacyResourceOwnerValidation"
	// DisableReferObjectsFromURL if set, the url ref objects will be disallowed
	DisableReferObjectsFromURL featuregate.Feature = "DisableReferObjectsFromURL"

	// ApplyResourceByUpdate enforces the modification of resource through update requests.
	// If not set, the resource modification will use patch requests (three-way-strategy-merge-patch).
	// The side effect of enabling this feature is that the request traffic will increase due to
	// the increase of bytes transferred and the more frequent resource mutation failure due to the
	// potential conflicts.
	// If set, KubeVela controller will enforce strong restriction on the managed resource that external
	// system would be unable to make modifications to the KubeVela managed resource. In other words,
	// no merge for modifications from multiple sources. Only KubeVela keeps the Source-of-Truth for the
	// resource.
	ApplyResourceByUpdate featuregate.Feature = "ApplyResourceByUpdate"

	// AuthenticateApplication enable the authentication for application
	AuthenticateApplication featuregate.Feature = "AuthenticateApplication"
	// GzipResourceTracker enables the gzip compression for ResourceTracker. It can be useful if you have large
	// application that needs to dispatch lots of resources or large resources (like CRD or huge ConfigMap),
	// which at the cost of slower processing speed due to the extra overhead for compression and decompression.
	GzipResourceTracker featuregate.Feature = "GzipResourceTracker"
	// ZstdResourceTracker enables the zstd compression for ResourceTracker.
	// Refer to GzipResourceTracker for its use-cases. It is much faster and more
	// efficient than gzip, about 2x faster and compresses to smaller size.
	// If you are dealing with very large ResourceTrackers (1MB or so), it should
	// have almost NO performance penalties compared to no compression at all.
	// If dealing with smaller ResourceTrackers (10KB - 1MB), the performance
	// penalties are minimal.
	ZstdResourceTracker featuregate.Feature = "ZstdResourceTracker"

	// GzipApplicationRevision serves the same purpose as GzipResourceTracker,
	// but for ApplicationRevision.
	GzipApplicationRevision featuregate.Feature = "GzipApplicationRevision"
	// ZstdApplicationRevision serves the same purpose as ZstdResourceTracker,
	// but for ApplicationRevision.
	ZstdApplicationRevision featuregate.Feature = "ZstdApplicationRevision"

	// ApplyOnce enable the apply-once feature for all applications
	// If enabled, no StateKeep will be run, ResourceTracker will also disable the storage of all resource data, only
	// metadata will be kept
	ApplyOnce featuregate.Feature = "ApplyOnce"

	// MultiStageComponentApply enable multi-stage feature for component
	// If enabled, the dispatch of manifests is performed in batches according to the stage
	MultiStageComponentApply featuregate.Feature = "MultiStageComponentApply"

	// PreDispatchDryRun enable dryrun before dispatching resources
	// Enable this flag can help prevent unsuccessful dispatch resources entering resourcetracker and improve the
	// user experiences of gc but at the cost of increasing network requests.
	PreDispatchDryRun featuregate.Feature = "PreDispatchDryRun"
