Performance for both OLTP and OLAP queries is important. Which of the following designs would you suggest to the company?
Options
- AUse a NoSQL data store such as MongoDB or Cloudant on the cloud to provide needed scalability
- BUse DB2 Data Partition Feature (DPF), partitioning all tables into different partitions
- CUse DB2 Data Partition Feature (DPF), only partitioning the 10 tables where Analytics will be run
- DUse DB2 with BLU Acceleration, use columnar store for the 10 tables where Analytics will be run
