Ed Anuff commented on CASSANDRA-2231: ------------------------------------- If you can add the -1, 0, 1 e-o-c suggestion, then I'm good with this. We've been using a preview version of your patch that we put up at https://github.com/riptano/hector-composite to make sure it works. So far it seems to meet every use case, with the exception of the previous questions from April 4 which you correctly pointed out couldn't be solved the way we were suggesting. So, I'm all for getting this out as soon as possible. > 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: CompositeType-and-DynamicCompositeType.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.
