[jira] [Commented] (SOLR-13220) Add connect Streaming Expression to
create cached JDBC connections
[ https://issues.apache.org/jira/browse/SOLR-13220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16808103#comment-16808103 ]
Gus Heck commented on SOLR-13220:
---------------------------------
Not saying this is a bad idea, but just want to note that it sounds like it would have some security implications. Once used, it sounds like this creates an authenticated connection that can be a target for expression injection attacks (replacing guessing name/passoword with guessing the connection name). Just something users should be aware of.

> Key: SOLR-13220
> URL: https://issues.apache.org/jira/browse/SOLR-13220
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Joel Bernstein
> Assignee: Joel Bernstein
> Priority: Major
>
> Currently the *jdbc* Streaming Expression requires that username, password and URL parameters are set to operate. This ticket will allow users to configure JDBC connections using the new *connect* Streaming Expression.
> The *jdbc* Streaming Expression will be changed to use the cached connections rather than accepting parameters directly.
> The *parallel* Streaming Expression can be used to setup connections on each node of a collection.
> The *Apache Hive* JDBC driver will also be included with Apache Solr as part of this ticket to allow seamless out-of-the-box connection to Apache Hive.
> Syntax:
> {code:java}
> connect(connectionName, url="", username="", password=""){code}
