     [ https://issues.apache.org/jira/browse/ARROW-1795?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Lu Qi  updated ARROW-1795:
--------------------------
    Description: 
say, we have total memory 8 G , we have input 5G data, then comes another 6G data, 
if we choose to evict space 6G , it will throw exception saying that
no object can be free. This is because we didn't count the 3G remaining
space .If we count this remaining 3G , we need to ask only 3G,thus
we can evict the 5G and we are still alive .
