Limited Realtime Support
Dashboards and other applications that require streaming data and alerts often demand realtime or near-realtime data transmissions. Many open source Big Data solutions and tools are batch-oriented; however, there is a new generation of realtime capable open source tools that have support for streaming data analysis. Many of the realtime data analysis solutions that do exist are proprietary. Approaches that achieve near-realtime results often process transactional data as it arrives and combine it with previously summarized batch-processed data.
