Example 1 with IndexPopulationProgress

use of org.neo4j.graphdb.schema.IndexPopulationProgress in project neo4j by neo4j.

the class SchemaImplTest method testGetIndexPopulationProgress.

@Test
void testGetIndexPopulationProgress() throws Exception {
    assertFalse(indexExists(USER_LABEL));
    // Create some nodes
    try (Transaction tx = db.beginTx()) {
        Label label = Label.label("User");
        // Create a huge bunch of users so the index takes a while to build
        for (int id = 0; id < 100000; id++) {
            Node userNode = tx.createNode(label);
            userNode.setProperty("username", "user" + id + "@neo4j.org");
        }
        tx.commit();
    }
    // Create an index
    IndexDefinition indexDefinition;
    try (Transaction tx = db.beginTx()) {
        Schema schema = tx.schema();
        indexDefinition = schema.indexFor(USER_LABEL).on("username").create();
        tx.commit();
    }
    // Get state and progress
    try (Transaction tx = db.beginTx()) {
        Schema schema = tx.schema();
        Schema.IndexState state;
        IndexPopulationProgress progress;
        do {
            state = schema.getIndexState(indexDefinition);
            progress = schema.getIndexPopulationProgress(indexDefinition);
            assertTrue(progress.getCompletedPercentage() >= 0);
            assertTrue(progress.getCompletedPercentage() <= 100);
            Thread.sleep(10);
        } while (state == Schema.IndexState.POPULATING);

        assertEquals(100.0, progress.getCompletedPercentage(), 0.0001);
    }
}
