2. © 2015 Jet Infosystems 2 Parallel Processing of Data Parallel processing is the main principle of big data computing Clusters with hundreds of nodes compute the Physics data In databases the parallel querying methods for SQL and Non-SQL Databases can be different, this presentation focuses on SQL DB (first of all – Oracle as a leader in databases) In databases area there are two main approaches for clusters in architecture: Shared Nothing and Shared Everything

3. © 2015 Jet Infosystems 3 Shared Nothing Cluster Every computing node has its own storage and data, the coordinator distributes the query between nodes and aggregates the results Shared Noting Clusters are used for parallel processing in all Non-SQL Databases and most SQL Databases For SQL Databases this approach is often called MPP (Massive Parallel Processing): Teradata, IBM Netezza, EMC Green Plum The main benefit is the absolute scalability, but cluster reconfigurations and multi-table join queries are the real problems for MPP

4. © 2015 Jet Infosystems 4 Shared Everything Cluster All cluster nodes query the data from shared storage, in any case the memory is shared between nodes with special technology The best-known implementation is RAC (Real Application Clusters) – Oracle Database Enterprise Edition Option No limitation for multi-table join queries and easy cluster reconfiguration, but the scalability of RAC needs special testing
