     [ https://issues.apache.org/jira/browse/CARBONDATA-2184?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Zhichao  Zhang updated CARBONDATA-2184:
---------------------------------------
    Description:
The description in [SPARK-21860|https://issues.apache.org/jira/browse/SPARK-21860]:
In `HeapMemoryAllocator`, when allocating memory from pool, and the key of pool is memory size.
Actually some size of memory ,such as 1025bytes,1026bytes,......1032bytes, we can think they are the same，because we allocate memory in multiples of 8 bytes.
In this case, we can improve memory reuse.
