Here are 5 things to know about BigInsights on System z. For much more, read the IBM Redbooks Solution Guid
1. Business Critical Hadoop - when good enough is not good enough.
IBM InfoSphere BigInsights elevates “good enough” Hadoop to an enterprise ready business critical analytics solution. IBM InfoSphere BigInsights for Linux on System z combined with IBM InfoSphere System z Connector for Hadoop give customers two key advantages:
2. BigInsights - Big Value-add
IBM InfoSphere BigInsights provides advanced software capabilities not found in competing Hadoop distributions. Among these capabilities are:
Big SQL, Big R, Big Sheets, Text Analytics Accelerators, Machine Data Accelerators, Social Data Accelerators, Adaptive MapReduce, IBM GPFS FPO (depending on version)
3. Virtualized storage
InfoSphere BigInsights clusters deployed on the mainframe will typically be deployed across several nodes. Performance in Hadoop is a function of the system resources assigned to each node as well as the number of nodes participating in the cluster. In traditional Hadoop clusters on Intel environments, total storage requirements also drive the size of the cluster. Total storage is less of a consideration in System z environments because the underlying storage is already virtualized.
4. DB2 for z/OS Integration
DB2 for z/OS provides user-defined functions that simplify the integration between DB2 applications and InfoSphere BigInsights. Among these user-defined functions are JAQL_SUBMIT and HDFS_READ, a table level function. SQL queries can invoke HDFS queries and pull the result sets back into predefined DB2 for z/OS tables.
5. Point and click data movement - No programming required
IBM InfoSphere System z Connector for Hadoop is a point and click graphical interface that users can easily extract data from z/OS sources, including IBM DB2® for z/OS, IBM IMS™, VSAM, and various system and application log files, without the need for mainframe-based SQL queries, custom programming, or specialized skills. The tool transforms that native data into an HDFS readable format, translates EBCDIC to ASCII automatically for BigInsights and other supported Hadoop distributions on or off the mainframe.
