Kestrel. Twitter’s Robey Pointer rewrote their Starling message queue in 1500 lines of Scala, adding reliable fetch (where consumers can confirm their receipt of an item) and blocking fetches, which reduce the need for consumers to poll for updates (and hence solve my only beef with the original Starling). I haven’t tried running this on a low spec VPS yet but it looks very promising.
