Workload management
• Allows balancing and management of different workload types (OLAP,
ETL, etc.)
• Allows creation of workload classes to control resources for each class
There are several levels and options of configuring and controlling
resources
• CPU at the OS level – for MDC and multi-host systems
• CPU at HANA system level
• Global setting to limit memory use of expensive SQL
• Configuring workload class and mapping (new in SPS12)
For more detail, see section 4.7 of SPS12 Administration Guide

8. Workload Class and Mapping
Two steps in workload management within HANA, through
SQL or HANA Cockpit
1. Create workload class, with the following attributes
• Priority – allows prioritizing statements, form 0 (lowest) to 9
highest, with default of 5
• Thread limit – number of parallel JobWorker threads per
statement
• Limit memory usage of a SQL statement
2. Map a client (e.g. database user, application name, etc.) to
a workload class

14. Performance - Capture and Replay
The Capture and Replay features allows analysis of workload, for several
purposes, e.g. simulation of impact of changing either hardware resource or
software configuration.
Reference:
• Capturing and Replaying Workloads - by the SAP HANA Academy ...
Prerequisite:
