Supporting supercolumns to allow multiple counters per row, but requiring encoding with a custom comparator for deeper nesting, seems like a reasonable compromise to me. Ryan, while this obviously isn't ideal from your perspective of already having code written against supercolumns-of-counters, is it something you could live with? In exchange we get 1072 + 1210 + 1397 + 1375 + ConsistencyLevel support for substantially less code (= less complexity and special cases) than 1072 alone. -- Jonathan Ellis Project Chair, Apache Cassandra co-founder of Riptano, the source for professional Cassandra support http://riptano.com
