In distributed robotics, there's a lot of things that go 1) pull data, 2) check timestamp on data to see if it's "fresh enough" to be considered. Redis solves that so naturally with TTL that it's not even worth considering message queues, dbs, or ROS topics for this. Yet, almost nobody does it that way from what I can see (I mean, we did, and it was fine). |
