Examples with Vertex org.apache.flink.runtime.topology.Vertex used on opensource projects

Example 1 with Vertex

use of org.apache.flink.runtime.topology.Vertex in project flink by apache.

the class DefaultScheduler method deployOrHandleError.

private BiFunction<Object, Throwable, Void> deployOrHandleError(final DeploymentHandle deploymentHandle) {
    final ExecutionVertexVersion requiredVertexVersion = deploymentHandle.getRequiredVertexVersion();
    final ExecutionVertexID executionVertexId = requiredVertexVersion.getExecutionVertexId();
    return (ignored, throwable) -> {
        if (executionVertexVersioner.isModified(requiredVertexVersion)) {
            log.debug("Refusing to deploy execution vertex {} because this deployment was " + "superseded by another deployment", executionVertexId);
            return null;
        }
        if (throwable == null) {
            deployTaskSafe(executionVertexId);
        } else {
            handleTaskDeploymentFailure(executionVertexId, throwable);
        }
        return null;
    };
}

Example 2 with Vertex

use of org.apache.flink.runtime.topology.Vertex in project flink by apache.

the class DefaultScheduler method assignResource.

private BiFunction<LogicalSlot, Throwable, LogicalSlot> assignResource(final DeploymentHandle deploymentHandle) {
    final ExecutionVertexVersion requiredVertexVersion = deploymentHandle.getRequiredVertexVersion();
    final ExecutionVertexID executionVertexId = deploymentHandle.getExecutionVertexId();
    return (logicalSlot, throwable) -> {
        if (executionVertexVersioner.isModified(requiredVertexVersion)) {
            if (throwable == null) {
                log.debug("Refusing to assign slot to execution vertex {} because this deployment was " + "superseded by another deployment", executionVertexId);
                releaseSlotIfPresent(logicalSlot);
            }
            return null;
        }
        // a task which is about to cancel in #restartTasksWithDelay(...)
        if (throwable != null) {
            throw new CompletionException(maybeWrapWithNoResourceAvailableException(throwable));
        }
        final ExecutionVertex executionVertex = getExecutionVertex(executionVertexId);
        executionVertex.tryAssignResource(logicalSlot);
        startReserveAllocation(executionVertexId, logicalSlot.getAllocationId());
        return logicalSlot;
    };
