Subject [jira] Commented: (CHUKWA-396) clean up add command syntax
Date Wed, 30 Sep 2009 18:17:23 GMT


Ari Rabkin commented on CHUKWA-396:

I'd like to propose the following change: the start location will be zero by default, and
to start reading from offset xyz, you'd need to say @xyz at the end of the add command.  Anything
before the '@' is part of the argument to the adaptor; anything after is an offset.  This
will be fairly easy to code. However, this change is BACKWARDS INCOMPATIBLE. So I'd prefer
to make it sooner rather than latter, but I do think it's worth doing.

> Currently, the add command syntax is a little yucky.  In particular, requiring a 0 at
end in the default case of "start from the beginning" is obnoxious and error-prone.
