func UnionMapsWithOverride(map1 map[string]string, map2 map[string]string) map[string]string

UnionMapsWithOverride unions two maps into one. If both maps are empty or nil, return an empty map. If both maps share the same key, the value in map2 overrides the value in map1.

func UpdateDatasetCondition 

func UpdateDatasetCondition(conditions []datav1alpha1.DatasetCondition, condition datav1alpha1.DatasetCondition) []datav1alpha1.DatasetCondition

SetDatasetCondition updates the dataset to include the provided condition. If the condition that we are about to add already exists and has the same status and reason then we are not going to update.

func UpdateMountStatus added in v0.6.0 

func UpdateMountStatus(client client.Client, name string, namespace string, phase datav1alpha1.DatasetPhase) error

UpdateMountStatus updates the mount status of the dataset according to the given phase

func UpdateRuntimeCondition 

func UpdateRuntimeCondition(conditions []data.RuntimeCondition, condition data.RuntimeCondition) []data.RuntimeCondition

UpdateRuntimeCondition updates the runtime to include the provided condition. If the condition that we are about to add already exists and has the same status and reason then we are not going to update.

Types

type UFSPathBuilder added in v0.6.0 

type UFSPathBuilder struct{}

func (UFSPathBuilder) GenAlluxioUFSRootPath added in v0.6.0 

func (u UFSPathBuilder) GenAlluxioUFSRootPath(items []datav1alpha1.Mount) (string, *datav1alpha1.Mount)

GenAlluxioUFSRootPath determines which mount point should be mounted on the root path of the unified namespace in Alluxio engine. Commonly there are two cases:

  1. If a `mount` item is the only item defined in `dataset.sepc.mounts[*]` and its ufs path equals to "/", its `mountpoint` should be on the root path. e.g. alluxio fs mount s3://mybucket /
  2. Otherwise, pick `/underFSStorage` as the default root path. e.g. alluxio fs mount /underFSStorage / && alluxio fs mount s3://mybucket /mybucket

func (UFSPathBuilder) GenLocalStoragePath added in v0.6.0 

func (u UFSPathBuilder) GenLocalStoragePath(curMount datav1alpha1.Mount) string

generate local storage path by mount info

func (UFSPathBuilder) GenUFSPathInUnifiedNamespace added in v1.0.2 

func (u UFSPathBuilder) GenUFSPathInUnifiedNamespace(mount datav1alpha1.Mount) string

GenUFSPathInUnifiedNamespace generates a path in the cache engine's unified namespace for the given mount. It follows the convention defined internally by Fluid:

1. if `dataset.spec.mounts[*].path` is set to a absolute path, pick `path`. 2. otherwise, pick `/{dataset.spec.mounts[*].name}`

func (UFSPathBuilder) GetLocalStorageRootDir added in v0.6.0 

func (u UFSPathBuilder) GetLocalStorageRootDir() string

this value will be the default value for the alluxio configuration: 

alluxio.master.mount.table.root.ufs

e.g. : 

$ alluxio fs mount
/underFSStorage  on  /  (local, capacity=0B, used=-1B, not read-only, not shared, properties={})
