[datatable-help] Merging where key is large

[Damian Betebenner]

Amazing package! Was wondering how to use data table with keys that exceed the max size of a 32 bit integer. I have unique person identifiers that are 10 digits and that of exceed 2e-09. I've converted that "integer" to a factor but the hit on performance and object size using that solution isn't very good.

Any insights greatly appreciated,

Best,

Damian
