DatasetService

public DatasetService(org.springframework.web.client.RestTemplate restTemplate,
                      DataStoreService dataStoreService)

Method Detail

getDatasetManifest

public DatasetManifest getDatasetManifest(Project project,
                                          String datasetId)

Obtains manifest from given project by given datasetId

Parameters:

project - project to which manifest belongs

datasetId - id of dataset

Returns:

manifest for dataset

Throws:

DatasetNotFoundException - when manifest can't be found (doesn't exist)

DatasetException - in case the API call failure

loadDataset

public FutureResult<Void> loadDataset(Project project,
                                      DatasetManifest manifest,
                                      InputStream dataset)

Loads dataset into platform. Uploads given dataset and manifest to staging area and triggers ETL pull. The call is asynchronous returning FutureResult to let caller wait for results. Uploaded files are deleted from staging area when finished.

Parameters:

project - project to which dataset belongs

manifest - dataset manifest

dataset - dataset to upload

Returns:

FutureResult of the task, which can throw DatasetException in case the ETL pull task fails

Throws:

DatasetException - if there is a problem to serialize manifest or upload dataset

loadDataset

public FutureResult<Void> loadDataset(Project project,
                                      String datasetId,
                                      InputStream dataset)

Gets DatasetManifest (using getDatasetManifest(com.gooddata.project.Project, String) first and then calls loadDataset(com.gooddata.project.Project, DatasetManifest, java.io.InputStream)

Parameters:

project - project to which dataset belongs

datasetId - datasetId to obtain a manifest

dataset - dataset to upload

Returns:

FutureResult of the task

loadDatasets

public FutureResult<Void> loadDatasets(Project project,
                                       DatasetManifest... datasets)

loadDatasets

public FutureResult<Void> loadDatasets(Project project,
                                       Collection<DatasetManifest> datasets)

Loads datasets into platform. Uploads given datasets and their manifests to staging area and triggers ETL pull. The call is asynchronous returning FutureResult to let caller wait for results. Uploaded files are deleted from staging area when finished.

Parameters:

project - project to which dataset belongs

datasets - map dataset manifests

Returns:

FutureResult of the task, which can throw DatasetException in case the ETL pull task fails

Throws:

DatasetException - if there is a problem to serialize manifest or upload dataset

listDatasets

@Deprecated
public Collection<Dataset> listDatasets(Project project)

Deprecated. use listDatasetLinks(Project) instead

Lists datasets (links) in project. Returns empty list in case there are no datasets.

Parameters:

project - project to list datasets in

Returns:

collection of dataset links or empty list

listDatasetLinks

public Collection<AboutLinks.Link> listDatasetLinks(Project project)

Lists datasets (links) in project. Returns empty list in case there are no datasets.

Parameters:

project - project to list datasets in

Returns:

collection of dataset links or empty list

optimizeSliHash

public FutureResult<Void> optimizeSliHash(Project project)

Optimize SLI hash. This feature is useful only if data warehouse was reduced somehow. Remove unused values from the existing SLI hash.

Parameters:

project - project to optimize SLI hash in

Returns:

FutureResult of the task

updateProjectData

public FutureResult<Void> updateProjectData(Project project,
                                            String maqlDml)

Update project data with the given update script (MAQL). This method can be used for data manipulation only, for model changes use ModelService.updateProjectModel(com.gooddata.project.Project, com.gooddata.model.ModelDiff).

Parameters:

project - project to be updated

maqlDml - update script to be executed in the project

Returns:
