Subject [jira] [Commented] (HBASE-10771) Primitive type put/get APIs in ByteRange
Date Sat, 29 Mar 2014 03:56:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10771?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13951743#comment-13951743

stack commented on HBASE-10771:

[~ndimiduk] What upstream project you thinking?  And what we need to adopt netty types?  Prove
that an async server better than one that starts out w/ hundreds of handlers?  Or you mean
netty ByteBuf?  When you say "...Can we not resolve these difficulties using subclasses, helper/utility
methods, and/or reflection?", do you mean subclasses of netty types or ByteBuffer or do you
mean subclass of ByteRange?

On why BR:

bq. ...reusable instances within a tight loop of compactions, simple(r) interface – something
I myself violated in introducing PositionedByteRange, and more relevant comparable implementation

On being reusable, nioByteBuffer and nettyByteBuf both fail this requirement.

What is simple(r) interface?  Looks like we are fast undoing this one w/ all the additions
being made herein.

.... and "...more relevant comparable implementation" prevails.

Which we seem to argue proceed with BR... but we need to fix the javadoc up in BR so it aligns
w/ these additions.

> While doing HBASE-10713 I came across the need to write int/long (and read also) from
a ByteRange.  CellBlocks are backed by ByteRange. So we can add such APIs.
> Also as per HBASE-10750  we return a ByteRange from MSLAB and also discussion under HBASE-10191
suggest we can have BR backed HFileBlocks etc.
