[chef] Re: Data Bag Meta Data

[John Keiser < >]

I don't believe the API has a way to do this.  However, if your main pain point is the time it takes to process the data bag (rather than the time it takes to retrieve it), you can get the checksum of a string like this:

require 'digest/md5'

Digest::MD5.hexdigest(str)

In that case, you could download the data bag items, checksum them, and compare with the last time you processed.

I know that there are upcoming APIs that will probably help with this.

Is there a way to obtain the meta data of a data bag object? For example, a way to get the time stamp of the last update or a check sum of the object.

I have hundreds of nodes that will be processing the elements of the data bag, which could be hundreds, and I want a way to filter out those which have already been processed. If the data bag item had been changed since the last run, I want to make sure it is processed.
