Query Execution Source Abstraction Virtual Modelling Business Delivery Query Optimizer Security & Governance Query Engine Delegate processing to data sources ▪ Transparently switch workloads according to cost or performance Most advanced execution engine for distributed scenarios ▪ Unique techniques automatically rewrite user queries to maximize pushdown ▪ Leverage MPP capabilities of data sources to deal with large data volumes Advancing Caching / Acceleration Mechanisms ▪ Selectively materialize subsets of the data for protecting data sources and query acceleration
- 8. 8 Integrated ETL / ELT Support: Remote Tables Create table in any location Load with data from any other data source Examples: • Data Lake management • Replicate data in lake when needed • Data Science • Move data to Spark after initial analysis • Cloud Migrations • Replicate and update data to cloud system SCH Often triggered from Scheduler
