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 sameļ¼because we allocate memory in multiples of 8 bytes.
In this case, we can improve memory reuse.
> Improve memory reuse for heap memory in `HeapMemoryAllocator`
