## How to check LRU cache memory footprint?
To observe the LRU cache memory footprint in the logs, configure the below
properties in log4j.properties file.
```
-log4j.logger.org.apache.carbondata.core.memory.UnsafeMemoryManager = DEBUG
log4j.logger.org.apache.carbondata.core.cache.CarbonLRUCache = DEBUG
```
-These properties will enable the DEBUG log for the CarbonLRUCache and
UnsafeMemoryManager which will print the information of memory consumed using
which the LRU cache size can be decided. **Note:** Enabling the DEBUG log will
degrade the query performance.

configured to observe the current cache size.
