Distinct Performance Challenges
Due to the volumes of data that some Big Data solutions are required to process, performance is often a concern. For example, large datasets coupled with complex search algorithms can lead to long query times. Another performance challenge is related to network bandwidth. With increasing data volumes, the time to transfer a unit of data can exceed its actual data processing time, as shown in Figure 3.4.
Figure 3.4 Transferring 1 PB of data via a 1-Gigabit LAN connection at 80% throughput will take approximately 2,750 hours.
