Challenges in Data Analytics:
Different application scenarios need different storage solutions: HBASE is ideal for point query scenarios but unsuitable for multi-dimensional queries. MPP is suitable for data warehouse scenarios but engine and data are coupled together which hampers scalability. OLAP stores used in BI applications perform best for Aggregate queries but full scan queries perform at a sub-optimal performance. Moreover, they are not suitable for real-time analysis. These distinct systems lead to low resource sharing and need different pipelines for data and application management.
