Examples with SessionId io.atomix.primitive.session.SessionId used on opensource projects

Example 1 with SessionId

use of io.atomix.primitive.session.SessionId in project atomix by atomix.

the class RaftServiceManager method applyOpenSession.

/**
 * Applies an open session entry to the state machine.
 */
private long applyOpenSession(Indexed<OpenSessionEntry> entry) {
    PrimitiveType primitiveType = raft.getPrimitiveTypes().get(entry.entry().serviceType());
    if (primitiveType == null) {
        throw new RaftException.UnknownService("Unknown service type " + entry.entry().serviceType());
    }
    // Get the state machine executor or create one if it doesn't already exist.
    RaftServiceContext service = getOrInitializeService(PrimitiveId.from(entry.index()), raft.getPrimitiveTypes().get(entry.entry().serviceType()), entry.entry().serviceName());
    if (service == null) {
        throw new RaftException.UnknownService("Unknown service type " + entry.entry().serviceType());
    }
    SessionId sessionId = SessionId.from(entry.index());
    RaftSession session = raft.getSessions().addSession(new RaftSession(sessionId, NodeId.from(entry.entry().memberId()), entry.entry().serviceName(), primitiveType, entry.entry().readConsistency(), entry.entry().minTimeout(), entry.entry().maxTimeout(), entry.entry().timestamp(), service, raft, threadContextFactory));
    return service.openSession(entry.index(), entry.entry().timestamp(), session);
}

Example 2 with SessionId

use of io.atomix.primitive.session.SessionId in project atomix by atomix.

the class SessionIdTest method testSessionId.

@Test
public void testSessionId() throws Exception {
    SessionId sessionId = SessionId.from(1);
    assertEquals(Long.valueOf(1), sessionId.id());
}

Example 3 with SessionId

use of io.atomix.primitive.session.SessionId in project atomix by atomix.

the class RaftServiceContext method installSnapshot.

/**
 * Installs a snapshot.
 */
public void installSnapshot(SnapshotReader reader) {
    log.debug("Installing snapshot {}", reader.snapshot().index());
    // Skip the service ID
    reader.skip(Bytes.LONG);
    PrimitiveType primitiveType = raft.getPrimitiveTypes().get(reader.readString());
    String serviceName = reader.readString();
    int sessionCount = reader.readInt();
    for (int i = 0; i < sessionCount; i++) {
        SessionId sessionId = SessionId.from(reader.readLong());
        NodeId node = NodeId.from(reader.readString());
        ReadConsistency readConsistency = ReadConsistency.valueOf(reader.readString());

        long maxTimeout = reader.readLong();
        long sessionTimestamp = reader.readLong();
        // Only create a new session if one does not already exist. This is necessary to ensure only a single session
        // is ever opened and exposed to the state machine.
        RaftSession session = raft.getSessions().addSession(new RaftSession(sessionId, node, serviceName, primitiveType, readConsistency, minTimeout, maxTimeout, sessionTimestamp, this, raft, threadContextFactory));
        session.setRequestSequence(reader.readLong());
        session.setCommandSequence(reader.readLong());
        session.setEventIndex(reader.readLong());
        session.setLastCompleted(reader.readLong());
        session.setLastApplied(reader.snapshot().index());
