Examples with RaftGroupListener org.apache.ignite.raft.client.service.RaftGroupListener used on opensource projects

Example 1 with RaftGroupListener

use of org.apache.ignite.raft.client.service.RaftGroupListener in project ignite-3 by apache.

the class ItTablePersistenceTest method createListener.

/**
 * {@inheritDoc}
 */
@Override
public RaftGroupListener createListener(ClusterService service, Path workDir) {
    return paths.entrySet().stream().filter(entry -> entry.getValue().equals(workDir)).map(Map.Entry::getKey).findAny().orElseGet(() -> {
        TableTxManagerImpl txManager = new TableTxManagerImpl(service, new HeapLockManager());
        // Init listener.
        txManager.start();
        PartitionListener listener = new PartitionListener(UUID.randomUUID(), new VersionedRowStore(new ConcurrentHashMapPartitionStorage(), txManager));
        paths.put(listener, workDir);
        return listener;
    });
}

Example 2 with RaftGroupListener

use of org.apache.ignite.raft.client.service.RaftGroupListener in project ignite-3 by apache.

the class RaftServerImpl method processQueue.

/**
 * Process the queue.
 *
 * @param queue The queue.
 * @param clo   The closure.
 * @param <T>   Command type.
 */
private <T extends Command> void processQueue(BlockingQueue<CommandClosureEx<T>> queue, BiConsumer<RaftGroupListener, Iterator<CommandClosure<T>>> clo) {
    while (!Thread.interrupted()) {
        try {
            CommandClosureEx<T> cmdClo = queue.take();
            RaftGroupListener lsnr = cmdClo.listener();
            clo.accept(lsnr, List.<CommandClosure<T>>of(cmdClo).iterator());
        } catch (InterruptedException e0) {
            return;
        } catch (Exception e) {
            LOG.error("Failed to process the command", e);
        }
    }
}

Example 3 with RaftGroupListener

use of org.apache.ignite.raft.client.service.RaftGroupListener in project ignite-3 by apache.

the class LozaTest method testLozaStop.

/**
 * Checks that the all API methods throw the exception ({@link org.apache.ignite.lang.NodeStoppingException})
 * when Loza is closed.
 *
 * @throws Exception If fail.
 */
