The only way I see is get all the object keys, get all the objects, and
then merge the secondary index values.

Hello,
In Riak, is it possible to retrieve all of the keys of an index? I do not want
the object keys in this case, but rather the actual index keys.
I am not sure that I am using the correct terminology, but to illustrate, consider a Riak bucket
with the following objects, where "catalog" is indexed to "catalog_bin":
{'url':'http://www.google.com', 'catalog':'1001'}
{'url':'http://www.yahoo.com', 'catalog':'1001'}
{'url':'http://www.blah.com', 'catalog': 1002'}
{'url':'http://www.test123.com', 'catalog': 1002'}
{'url':'http://www.test12345.com', 'catalog': 1003'}
I would like to retrieve all of the keys for the index catalog_bin. From the
above example, that would be:
1001
1002
1003
To illustrate further, it would be the equivalent of the following in MySQL, if the above
data were to be in a table called "urls":
SELECT catalog FROM urls GROUP BY catalog;
I would appreciate any advice as to how to query for this in Riak, or if this
not feasible, then perhaps a suggestion for the best way to organize the data.
Thank you,
Jeff
