expensive statements trace - Details

• 
  Key Concepts: 
  Expensive Statements Trace is a feature of SAP HANA that allows users to identify and analyze the most expensive SQL statements that are executed in the system. It provides detailed information about the execution time, memory usage, and other performance metrics of each statement. This helps users to identify and optimize the most expensive statements, thus improving overall system performance. 
  
  How to use it: 
  Expensive Statements Trace can be enabled in SAP HANA by setting the trace level to “expensive” in the system configuration. Once enabled, it will log all expensive statements that are executed in the system. The log can then be analyzed to identify and optimize the most expensive statements. 
  
  Tips & Tricks: 
  When analyzing the log, it is important to look at both the execution time and memory usage of each statement. This will help to identify which statements are taking up the most resources and should be optimized first. Additionally, it is important to consider the context of each statement when optimizing it. For example, a statement that takes a long time to execute may not be worth optimizing if it is only used rarely.
