Subject [jira] [Commented] (ACCUMULO-2368) Addsplits to an offline table
Date Sat, 21 Jun 2014 16:06:24 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2368?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14039882#comment-14039882

Keith Turner commented on ACCUMULO-2368:
----------------------------------------

The purpose of this issue is to offer a faster way to split because the current code is not
fast enough.  I will run some experiments w/ 1.6.1-SNAPSHOT on a 20 node EC2 cluster this
coming week inorder to gain insight into the problems w/ the current code.  An alternative
to adding offline splits may be fixing whatever the current problems are, so users get the
benefit w/o making any changes to their code.   To know if this a viable solution we need
to understand what the current problems are, which is why I am planning on running some experiments.

> Currently a table must be online to addsplits. Firstly, it's relatively slow. Secondly,
it could be a LOT faster to do it to an offline table because it's just a few metadata writes
per split point.
