Subject [jira] [Commented] (HBASE-15506) FSDataOutputStream.write() allocates new byte buffer on each operation
Date Thu, 31 Mar 2016 04:46:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15219340#comment-15219340
] 

Lars Hofhansl commented on HBASE-15506:
---------------------------------------

nginx is implemented in C/C++.
We can easily find about as many articles and examples for it as we can find them against
it.

I am only saying that a statement like "heap allocations are bad" is simply not generally
true.
Let's test, have some numbers, and I will happily shut up about it (in fact if I was wrong
I will have learned something)
