Index on bigint or decimal(10,0)?

Hi,

I've been googling but couldn' find a concrete answer.

Have an ID column that can take up 10 digits and will be used in joins.

For PK/Index creation, what is the impact on performance (reading) if using bigint vs decimal(10,0)?

Bigint will take more space (8 bytes), but is it more performant when it's used in joins?

Thanks,

Foad
