the class BatchSender method asyncSendWithRetry.

public void asyncSendWithRetry(String requestId, int queueId, long snapshotId, long offset, OperationBatch operationBatch) {
    int partitionCount = metaService.getPartitionCount();
    Map<Integer, Builder> storeToBatchBuilder = new HashMap<>();

    for (OperationBlob operationBlob : operationBatch) {
        long partitionKey = operationBlob.getPartitionKey();
        if (partitionKey == -1L) {
            // replicate to all store node
            for (int i = 0; i < this.storeCount; i++) {
                StoreDataBatch.Builder batchBuilder = storeToBatchBuilder.computeIfAbsent(i, storeDataBatchBuilderFunc);
                batchBuilder.addOperation(-1, operationBlob);
