Subject [jira] [Commented] (ACCUMULO-650) Add table descriptions
Date Sun, 24 Mar 2013 03:11:14 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-650?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13611935#comment-13611935

Josh Elser commented on ACCUMULO-650:
-------------------------------------

Table ids aren't anything more than a hex one-up counter. Also, a clone is lazy in that doesn't
make a copy of the data until it changes as compared to the table it was cloned from (as in,
both tables will point to the same file on disk right after the clone).

Personally, I would expect a user doing something like..

{noformat}
> createtable foo
foo> desc -u 'full of foo!'
foo> insert bar bar bar bar
foo> clonetable foo bar
bar> desc -u 'full of bar!'
{noformat}

I guess I envision the common use case would be that someone clone a table, and then want
to update the description with why they cloned it. Mostly thinking out loud here too :)

> We should add a table description field, probably in zookeeper, to store an optional
field end users can use to provide their relevant information on the table.
