Sylvain Lebresne commented on CASSANDRA-2231: --------------------------------------------- bq. For parameterized behavior of comparators, my assumption is that this would work within the DynamicCompositeType as well? It would. bq. but ultimately we'd need a more robust comparator factory That's the idea. I intent to add this as part of CASSANDRA-2355. > Add CompositeType comparer to the comparers provided in > org.apache.cassandra.db.marshal > --------------------------------------------------------------------------------------- > > Key: CASSANDRA-2231 > URL: https://issues.apache.org/jira/browse/CASSANDRA-2231 > Project: Cassandra > Issue Type: Improvement > Components: Contrib > Affects Versions: 0.7.3 > Reporter: Ed Anuff > Assignee: Sylvain Lebresne > Priority: Minor > Fix For: 0.7.5 > > Attachments: 0001-Add-compositeType-and-DynamicCompositeType.patch, > 0001-Add-compositeType.patch, edanuff-CassandraCompositeType-1e253c4.zip > > > CompositeType is a custom comparer that makes it possible to create > comparable composite values out of the basic types that Cassandra currently > supports, such as Long, UUID, etc. This is very useful in both the creation > of custom inverted indexes using columns in a skinny row, where each column > name is a composite value, and also when using Cassandra's built-in secondary > index support, where it can be used to encode the values in the columns that > Cassandra indexes. One scenario for the usage of these is documented here: > http://www.anuff.com/2010/07/secondary-indexes-in-cassandra.html.
