looking for information on composite columns
Hi, I am looking for information/tutorials on the use of composite columns, including how to use it, what kind of indexing it can offer, and its advantage over super columns. I googled but came up with very little information. There is a blog article from high performance cassandra on the compositeType comparator, but the use case is a composite column name rather than a column value. Does anyone know of some good resources on this and is willing to share with me? Thanks. -- Y.
