the class PrimaryRole method executeQuery.

private CompletableFuture<ExecuteResponse> executeQuery(ExecuteRequest request) {
    // If the session doesn't exist, create and replicate a new session before applying the query.
    Session session = context.getSession(request.session());
    if (session == null) {
