Ben McCann commented on CASSANDRA-3281: --------------------------------------- I'm a little foggy on whether I was able to do things like index based on the value of a field contained within a protobuf. What I'm definitely missing now is basically the ability to set the validation_class for a column to ThriftType and then run a CQL query that can scan the table, deserialize the column, and select thrift structs where a certain field has a certain value. Super nice for debugging, running nightly reports, etc. > 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. -- This message is automatically generated by JIRA.
