    this.stormConfig = stormConfig;
    this.stellarProcessor = new StellarProcessor();
    this.fileNameFormat.prepare(stormConfig, topologyContext);
    if (syncPolicy != null) {
        // if the user has specified the sync policy, we don't want to override their wishes.
        syncPolicyCreator = new ClonedSyncPolicyCreator(syncPolicy);
    } else {
        // if the user has not, then we want to have the sync policy depend on the batch size.
        syncPolicyCreator = (source, config) -> new CountSyncPolicy(config == null ? 1 : config.getBatchSize(source));
    }
}
