Indices for non-linear look-ups about flatbuffers HOT 1 CLOSED

You don't need to even have it all in memory, using mmap you could very easily load only the parts that are touched. It can in theory even be streamed, but we'd need some code support for that.

As for indices, I agree that be awesome. It is already currently possible, i.e. you could construct a list of objects, then serialize also multiple vectors of offsets to these objects with different sorting orders. Alternatively, you can construct things like hashtables that are serializable (probably open addressing would be more space/time efficient than chaining in this case). I already had it on my idea list to be writing helper code for such things.
