I've a whole new respect for ElasticSearch. It's codebase is so insanely complex, that I'm seriously contemplating tracing out the flow on a big ass chart. Any suggestions on how you people work and debug so many asynchronous flows?

I have been working on a bug, for almost 6 days (to be read as 3 consecutive weekends), and the best I've done is, conceptually isolate where it's happening. I'm an open source noob, but I feel I've learnt a whole lot during sifting through ES' codebase. :)

Unidirectional data flow and immutability. The only way to handle it and not blow yourself up all the time.

As above, but also by utilising all available tools.

Not used ES, but have used webflux / reactor extensively. The tools that generate flow diagrams from stack traces are invaluable, as are spurious uses of .log() . Wouldn't be able to operate sanely without either of them.
