[jira] [Commented] (CASSANDRA-3281) Add an AbstractType anytype which stores meta data on a per column basis

["Ben McCann (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-3281?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13239973#comment-13239973 ] 

Ben McCann commented on CASSANDRA-3281:
---------------------------------------

BigTable has built-in support for Protocol Buffer, which is really nice because you can do things like store a serialized document in a compact manner and then search for it using something like CQL.  I'm really having a hard time with Cassandra because if I store Thrift/Protobuf/JSON it's completely opaque.  It's really not clear to me at the moment what the best practice for storing complex hierarchies in Cassandra is.  I think AnyType might be a bit too much, but built-in support for Thrift would be nice.

> A pet project of mine is an AbstractType for Cassandra that stores metadata of the type in the column. https://github.com/edwardcapriolo/Cassandra-AnyType
> I described my use case any my design decisions here. https://github.com/edwardcapriolo/Cassandra-AnyType/blob/master/README . The biggest cases were needing to support null and '' as keys, column names, and column values, however I also think the technique used to serialize Java Objects as JSON but compare as a Java object is novel. 
> Side node: (The AbstractType interface has changed multiple times between 0.6.X, 0.7.X, and 1.0.0-beta. I hope it stabilizes! ) 
> If people would like AnyType (or parts of it ) incorporated into Cassandra that would be great. I am willing to tweak change it based on other peoples ideas.
