Method Details

getFederationCatalog

public FederationCatalog getFederationCatalog()

Specified by:

getFederationCatalog in interface QueryProcContext

getFederationAccessMgr

public FederationAccessManager getFederationAccessMgr()

Specified by:

getFederationAccessMgr in interface QueryProcContext

getExecutorServiceForPlanTasks

public ExecutorService getExecutorServiceForPlanTasks()

Specified by:

getExecutorServiceForPlanTasks in interface QueryProcContext

getSourceAssignmentPrinter

public LogicalPlanPrinter getSourceAssignmentPrinter()

Description copied from interface: QueryProcContext

A plan printer to be used for printing the source assignment (which is the initial logical plan after source selection, before logical optimization). If source assignment printing is not requested by the user, then this method returns null.

Specified by:

getSourceAssignmentPrinter in interface QueryProcContext

getLogicalPlanPrinter

public LogicalPlanPrinter getLogicalPlanPrinter()

Description copied from interface: QueryProcContext

A plan printer to be used for printing the final logical plan that is the result of logical optimization. If logical plan printing is not requested by the user, then this method returns null.

Specified by:

getLogicalPlanPrinter in interface QueryProcContext

getPhysicalPlanPrinter

public PhysicalPlanPrinter getPhysicalPlanPrinter()

Description copied from interface: QueryProcContext

A plan printer to be used for printing the final physical plan that is the result of physical optimization. If physical plan printing is not requested by the user, then this method returns null.

Specified by:

getPhysicalPlanPrinter in interface QueryProcContext

getExecutablePlanPrinter

public ExecutablePlanPrinter getExecutablePlanPrinter()

Description copied from interface: QueryProcContext

A plan printer to be used for printing the executable plan, as produced from the final physical plan. If executable plan printing is not requested by the user, this method returns null.

Specified by:

getExecutablePlanPrinter in interface QueryProcContext

isExperimentRun

public boolean isExperimentRun()

Description copied from interface: QueryProcContext

Returns true if the query execution process is done as part of an experiment, in which case additional statistics need to be produced.

Specified by:

isExperimentRun in interface QueryProcContext

skipExecution

public boolean skipExecution()

Description copied from interface: QueryProcContext

Returns true if the user requested to skip the actual query execution. In this case, the query processor can stop after query planning.

Specified by:

skipExecution in interface QueryProcContext

getLogicalToPhysicalPlanConverter

public LogicalToPhysicalPlanConverter getLogicalToPhysicalPlanConverter()

Specified by:

getLogicalToPhysicalPlanConverter in interface QueryProcContextExt

getLogicalToPhysicalOpConverter

public LogicalToPhysicalOpConverter getLogicalToPhysicalOpConverter()

Specified by:

getLogicalToPhysicalOpConverter in interface QueryProcContextExt
