Example 2 with Configuration

use of org.neo4j.internal.batchimport.Configuration in project neo4j by neo4j.

Example 3 with Configuration

use of org.neo4j.internal.batchimport.Configuration in project neo4j by neo4j.

the class DynamicProcessorAssignerTest method shouldMoveProcessorFromOverlyAssignedStep.

@Test
void shouldMoveProcessorFromOverlyAssignedStep() {
    // GIVEN
    Configuration config = config(10, 5);
    // available processors = 2 is enough because it will see the fast step as only using 20% of a processor
    // and it rounds down. So there's room for assigning one more.

    StageExecution execution = executionOf(config, slowStep, fastStep);
    assigner.start(execution);
    // WHEN checking
    assigner.check(execution);
    // THEN one processor should have been moved from the fast step to the slower step
    assertEquals(2, fastStep.processors(0));
    assertEquals(3, slowStep.processors(0));
}

Example 4 with Configuration

use of org.neo4j.internal.batchimport.Configuration in project neo4j by neo4j.

the class DynamicProcessorAssignerTest method shouldMoveProcessorFromNotOnlyFastestStep.

@Test
void shouldMoveProcessorFromNotOnlyFastestStep() {
    // The point is that not only the fastest step is subject to have processors removed,
    // it's the relationship between all pairs of steps.
    // GIVEN
    Configuration config = config(10, 5);
    DynamicProcessorAssigner assigner = new DynamicProcessorAssigner(config);
