Hi, putAll just sends all data right away.
DataStreamer locally builds batches of 512 entries (configurable) and does an equivalent of "putAll" for the batches as they become full. DataStreamer also retries "putAll" if it fails. DataStreamer allows you to configure server-side processing of added data. DataStreamer blocks addData if remote nodes need more time to process data. Thus, if you have not a very big amount of static data then putAll shall be faster. If you have huge data set or need a server side processing then DataStreamer is a better option.
