I''m trying to import data from an existing database that relies on key/value pairs. I''d like to set up an ActionWebService server for this data and have that system send a message to me when it receives something new, but I''m unsure of a way to handle the parameter specifiers on my end. Each request will contain a variable-length list of key/value pairs, but ActionWebService seems as though it expects a structured list of parameters. As such, I''d have to explicitly expect a list of about 800 parameters from my client, and not only is that ridiculous, but not all the objects in the database have values for all the keys, so it''d just end up being empty sets being sent over the wire; hardly efficient. Am I going about this wrong or is this a limitation of AWS? Thanks, Adam -- Posted via http://www.ruby-forum.com/.
