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.
> Add an AbstractType anytype which stores meta data on a per column basis

> Key: CASSANDRA-3281
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3281
> Project: Cassandra
> Issue Type: New Feature
> Reporter: Edward Capriolo
> Priority: Minor
>
> 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.
