[jira] [Commented] (PHOENIX-4150) Adding a policy filter to whitelist the properties that allow to be passed to Phoenix

["Alex Araujo (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PHOENIX-4150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16151101#comment-16151101 ] 

Alex Araujo commented on PHOENIX-4150:
--------------------------------------

[~aertoria] adding a UserPropertiesPolicy interface with a default policy that allows all properties (current behavior) would be a good start. A new policy that allows whitelisted properties, or a factory that can find custom policies on the classpath might warrant their own Jira.

> Adding a policy filter to whitelist the properties that allow to be passed to Phoenix.
> Feature proposal:
> When user getting phoenix connection via
> Connection conn = DriverManager.getConnection(connectionString, properties);
> A properties whitelist policy will essentially check each properties that passed in (likely happen at PhoenixDriver.java), so that the un-allowed property will result in an exception been thrown.
> Similar to HBaseFactoryProvider, proposing have a interface for whitelist policy and a default impl that will by default allow all properties. User can override the impl for this interface to start using whitelist feature
