Examples with ReconfigurationErrorDetectedEvent com.couchbase.client.core.cnc.events.core.ReconfigurationErrorDetectedEvent used on opensource projects

Example 1 with ReconfigurationErrorDetectedEvent

use of com.couchbase.client.core.cnc.events.core.ReconfigurationErrorDetectedEvent in project couchbase-jvm-clients by couchbase.

the class Core method reconfigureDisconnectAll.

/**
 * This reconfiguration sequence takes all nodes and disconnects them.
 *
 * <p>This is usually called by the parent {@link #reconfigure()} when all buckets are closed which
 * points to a shutdown/all buckets closed disconnect phase.</p>
 */

    long start = System.nanoTime();
    Flux.fromIterable(new ArrayList<>(nodes)).flatMap(Node::disconnect).doOnComplete(nodes::clear).subscribe(v -> {
    }, e -> {
        clearReconfigureInProgress();
        eventBus.publish(new ReconfigurationErrorDetectedEvent(context(), e));
    }, () -> {
        clearReconfigureInProgress();
        eventBus.publish(new ReconfigurationCompletedEvent(Duration.ofNanos(System.nanoTime() - start), coreContext));
    });
}

Example 2 with ReconfigurationErrorDetectedEvent

use of com.couchbase.client.core.cnc.events.core.ReconfigurationErrorDetectedEvent in project couchbase-jvm-clients by couchbase.

the class Core method reconfigure.

/**
 * Reconfigures the SDK topology to align with the current server configuration.
 *
 * <p>When reconfigure is called, it will grab a current configuration and then add/remove
 * nodes/services to mirror the current topology and configuration settings.</p>
 *
 * <p>This is a eventually consistent process, so in-flight operations might still be rescheduled
 * and then picked up later (or cancelled, depending on the strategy). For those coming from 1.x,
 * it works very similar.</p>
