Hi tinytimothy2 ,
Analysis Services indeed employs caching to enhance query performance. When you execute a query, it tries to retrieve results from the cache first before hitting the underlying data source.
To understand why data isn’t in cache, consider the following tools:
- SQL Server Management Studio (SSMS): Use SSMS to execute the XMLA ClearCache command against specific levels (database, cube, dimension, table, or measure group).
- Monitoring Tools: Monitor system performance and resource usage to identify any processes affecting cache eviction.
- Profiler Traces: Set up profiler traces to capture query execution details and analyze cache behavior.
- Query Execution Plans: Examine query plans to identify bottlenecks or unexpected behavior.
- Event Logs: Check for any warnings or errors related to cache eviction.
