Hello, Is there any way to expire keys/rows in cassandra based on their last-modification timestamp (if such timestamp exists)? It will be ideal place to modify if cassandra has a task/thread that periodically goes through all keys in a node. GC deletion marker?
Without this kind of expiration-feature how can I go through all keys periodically to delete expired keys? I think one way is to do sliced range query then expire keys based on their time stamp. This seems to be doable but I need to switch to order preserve partitioner. Thanks, -Weijun
