[jira] Commented: (AVRO-76) Add plug-in mechanism for manipulating per-call metadata

["Doug Cutting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-76?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12728959#action_12728959 ] 

Doug Cutting commented on AVRO-76:
----------------------------------

Some quick comments:
 - Requestor and Responder should each support a list of plugins, not just a single plugin, so that one might implement authentication, authorization, tracing and other orthogonal mechanisms each as a plugin.
 - Plugins should be added with an addPlugin() method, not through constructors.  Over time, adding optional parameters leads to confusing parameter lists.  In the case of getClient(), we might change the signature to accept a Requestor
 - Metadata map should be passed as a parameter to the plugin's methods.
