I have one follow up question - is TTL a planned feature? Being able to set a TTL on the _stream itself_ and -also- on the messages would be extremely nice. While MAXLEN prevents a queue from being extremely large, I also want to remove "stale" data after a configurable time period.

Use case: A log of network latencies, where a user might currently `XREAD` with a timestamp 10 minutes in the past, would be able to save on memory usage by expiring log entries > 10 minutes, and then being able to `XREAD STREAMS strm 0` and let Redis (and therefore the infrastructure, not my code, manage data retention).

Also, how does this work re: evictions? Say a node is at max memory, will entire _streams_ be evicted, or (I hope) the oldest messages in the LRUed or LFUed queues.
