Examples with LatencyMinimizingServerSelector com.mongodb.selector.LatencyMinimizingServerSelector used on opensource projects

Example 1 with LatencyMinimizingServerSelector

use of com.mongodb.selector.LatencyMinimizingServerSelector in project mongo-java-driver by mongodb.

the class ServerSelectionSelectionTest method shouldPassAllOutcomes.

@Test
public void shouldPassAllOutcomes() {
    // skip this test because the driver prohibits maxStaleness or tagSets with mode of primary at a much lower level
    assumeTrue(!description.equals("max-staleness/server_selection/ReplicaSetWithPrimary/MaxStalenessWithModePrimary.json"));
