Henry Robinson on testing and fault discovery in distributed systems

'Let's talk about finding bugs in distributed systems for a bit.
These chaos monkey-style fault testing systems are all well and good, but by being application independent they're a very blunt instrument.
Particularly they make it hard to search the fault space for bugs in a directed manner, because they don't 'know' what the system is doing.
Application-aware scripting of faults in a dist. systems seems to be rarely used, but allows you to directly stress problem areas.
For example, if a bug manifests itself only when one RPC returns after some timeout, hard to narrow that down with iptables manipulation.
But allow a script to hook into RPC invocations (and other trace points, like DTrace's probes), and you can script very specific faults.
That way you can simulate cross-system integration failures, *and* write reproducible tests for the bugs they expose!
Anyhow, I've been doing this in Impala, and it's been very helpful. Haven't seen much evidence elsewhere.'

Binary message marshalling, client/server stubs generated by an IDL compiler, bidirectional binary protocol. CORBA is back from the dead!

Cap'n Proto
Cap’n Proto is an insanely fast data interchange format and capability-based RPC system. Think JSON, except binary. Or think Protocol Buffers, except faster. In fact, in benchmarks, Cap’n Proto is INFINITY TIMES faster than Protocol Buffers.

Basically, marshalling like writing an aligned C struct to the wire, QNX messaging protocol-style. Wasteful on space, but responds to this by suggesting compression (which is a fair point tbh). C++-only for now. I'm not seeing the same kind of support for optional data that protobufs has though. Overall I'm worried there's some useful features being omitted here...
