Interface IDerivedDataEngine

All Known Implementing Classes:

DerivedDataEngine

public interface IDerivedDataEngine

Derived data engine contains and controls all shared infrastructure of the derived data facility. It's assumed that the single EDT instance should work with a single instance The engine requires external management of its lifecycle after creation using start() and stop() methods

Method Summary

Method Details

createProvider

IDerivedDataBmProvider createProvider(String projectId,
 Collection<IDerivedDataConfigurationContributor> contributors,
 Set<String> filteredSegments,
 IDerivedDataServiceLockController lockController,
 Supplier<Boolean> synchronizationActiveStateSupplier,
 Supplier<IAsyncComputationExecutionContext> executionContextSupplier)

Creates a provider

Parameters:

projectId - The unique identifier of the owner project. Cannot be null

contributors - The set of derived data contributors. Cannot be null. Can be empty

filteredSegments - The set of segment ids that should be ommitted during the computation. Cannot be null. Can be empty

lockController - The DD external lock controller. Cannot be null

synchronizationActiveStateSupplier - The supplier which provides the status of the synchronization. Cannot be null

executionContextSupplier - The supplier which provides client-specific IAsyncComputationExecutionContext. Cannot be null

Returns:

The created DD provider. Cannot be null

setPermittedThreads

void setPermittedThreads(int permittedThreads)

Sets the maximum number of computation threads the DD subsystem should use at the moment. It's up to client to control reduction/increasing the number of used threads, the DD subsystem itself won't adjust the maximum number of used threads (though could use less then maximum in any given moment)

Parameters:

permittedThreads - The number of permitted threads. Must be a positive number

start

void start()

Starts the inactive engine. The single engine instance mustn't be started more then once. The engine should be in inactive state prior the start call

stop

void stop()

Stops the active engine. The single engine instance mustn't be stopped more then once. The engine should be in active state prior the stop call
