[jira] [Created] (CARBONDATA-1179) Improve the Object Size
calculation for Objects added to LRU cache
Raghunandan created CARBONDATA-1179:
---------------------------------------
Summary: Improve the Object Size calculation for Objects added to LRU cache
Key: CARBONDATA-1179
URL: https://issues.apache.org/jira/browse/CARBONDATA-1179
Project: CarbonData
Issue Type: Bug
Reporter: Raghunandan
Priority: Minor
Java Object model has a bigger overhead when loading the objects into memory.
The current way of estimating the object size by looking at the file size is not correct and gives wrong results.Moreover due to this calculation, we are storing more than the configured size for LRU cache.
Improve the ObjectSize calculation by using the spark SizeEstimator utility
