What happens if a redis stream grows beyond the machine's memory? Will old messages get swapped to disk?
Background: I want to use the messenger component of symfony, which can use redis as a message transport. However, their im plementation does only XADD and XREAD, so over time the stream would really grow large...

You may get better answers asking at the Redis Community https://redis.io/community or by searching StackOverflow . The most reliable answer is, of course, to do it yourself. Set up a VM or spare machine with minimal RAM and start writing. Watch with vmstat and other tools and see what happens to pageouts.
