Subject [jira] [Commented] (CASSANDRA-9499) Introduce writeVInt method to DataOutputStreamPlus
Date Tue, 16 Jun 2015 00:56:01 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9499?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14587256#comment-14587256

Ariel Weisberg commented on CASSANDRA-9499:
-------------------------------------------

I did all the changes except for trying to make readVInt faster. 

It isn't so simple which is why I didn't do it. I can't leave any padding (fake reads), and
I can't over consume (lost data). I would end up having to make things right after I have
figured out how many bytes I have actually consumed or alternatively I would have to make
a copy (which could easily be faster). This is much simpler, but if you think its necessary
I'll do it.

> CASSANDRA-8099 really could do with a writeVInt method, for both fixing CASSANDRA-9498
but also efficiently encoding timestamp/deletion deltas. It should be possible to make an
especially efficient implementation against BufferedDataOutputStreamPlus.
