Thanks for replying~ 但我觉得把Column:Qualifier的组合翻译为字段更好点 :) 有的人把Qualifier翻译成了修饰符，感觉怪怪的。 Jack Chan. A new Apache-Camel rider. sina-weibo:@for-each 发件人： Haosong Huang 发送时间： 2013-11-19 18:06 收件人： user 主题： Re: How to translate keyword 'Qualifier' into chinese? 翻译成字段 2013-11-19 下午3:10于 "Jack Chan" 写道

Re: HBase snapshots

Thanks for the detailed answers, Matteo. w.r.t. incremental snapshots, there is HBASE-7912. When Multi-WAL feature, HBASE-5699, is implemented, it would be more efficient to support capturing incremental changes as proposed by HBASE-7912. Cheers On Tue, Nov 19, 2013 at 9:13 AM, Matteo Bertozz
