[jira] [Commented] (ARROW-3493) [Java] Document BOUNDS_CHECKING_ENABLED

    [ https://issues.apache.org/jira/browse/ARROW-3493?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16647640#comment-16647640 ] 

Animesh Trivedi commented on ARROW-3493:
----------------------------------------

So, I propose that we

i) rename the variable from "drill.enable_unsafe_memory_access" to "arrow.enable_unsafe_memory_access"

ii) set the default to false. This can be enabled if user explicitly wants to debug and check ranges. 

iii) document this flag (and perhaps the netty one too) in the Java user documentation. 

If we agree then I will open a pull request.
