Subject [jira] [Commented] (CASSANDRA-3281) Add an AbstractType anytype which stores meta data on a per column basis
Date Thu, 29 Dec 2011 17:51:30 GMT


Jonathan Ellis commented on CASSANDRA-3281:

Is it accurate to say that conceptually, the main difference between AnyType and DynamicCompositeType
is that AnyType also includes type information for the value?

. 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.
