Github user HeartSaVioR commented on the issue: https://github.com/apache/storm/pull/1748 @vesense I manually tested that it works. Thanks for the great work! Btw, I'm seeing that only one fields are used for storing the value, but I guess some users occasionally would want to store the document as it is (not serialized to one field). I'm OK if there's specific reason to do it (for example, supporting schema matters) but if it's not, I feel "storing as it is" is more natural and what users expected without any configurations.
