custom IDs for distributed jobs

Is it possible to customize the ID type (I'd like strings) when
running the similarity/recommendations distributed jobs?

Thanks,

Hi Matt,

Unfortunately not, these jobs undertake a lot of mathematical operations
inside which use vectors keyed on ints. You can map your string ids to
ints before the job and remap them afterwards however.

Best,
Sebastian
