Subject [jira] [Commented] (HBASE-18232) Add variable size chunks to the MSLAB
Date Wed, 25 Oct 2017 07:26:04 GMT

Anastasia Braginsky commented on HBASE-18232:
---------------------------------------------

Hey [~anoop.hbase], [~ram_krish], [~eshcar], [~stack], [~ebortnik],

I would like to draw your attention to this Jumbo Chunks addition.
It passed the review about a month and a half ago, but may be you want to take a look again.
The QA runs successfully. 
One question, raised by Ram in review, is about cells bigger than 2GB. Such cells can not
generally be supported by MSLAB, as ByteBuffer is limitted to 2GB allocation. Does HBASE support
such cell size?

Thanks!
Anastasia
