Sequence input for CreateId() about idgen

[RobThree]

That's currently not supported and I don't see how this should be implemented in a generic way without sacrificing a lot of performance. You'd need to have an IGeneratorProvider which would return the 'shard' or 'generator' which would have to take some arbitrary value as input to be able to do it's work and then you'd also need an ISequenceProvider which would need a similar arbitrary input. That would, in turn, mean that CreateId() would need to be able to take some argument(s) etc.

Suggestions are welcome, but I don't see how this would be implemented without a major rewrite and/or breaking backcompat.

Also: since you're specifically asking for sequence: adding a modulo <value> essentially means "wrap around" which would result in collisions...

maybe something like simple CreateIdWithSequenceInput(long sequence) - without changing the CreateId() - however, I guess lenght has to be checked with sequence input and mask capacity for sequence. Regarding the modulo, I guess it should be the callers responsibility inputing the modulo-ed sequence value.

thank you for your feedback!

Isn't it easier, at that point, to implement your "own IdGen"? It isn't exactly rocket surgery, as you can see in the instagram post.
