Add skewness on data generated for foreign key

[lolegrand]

Hello 👋,

I don't find any answer so I'm asking here.

I'd like to generate a data that implement skewness over a cardinality between two tables, let's take an exemple:

Table phone :

[{
"id": "1",
"name": "iphonX"
},
{
"id": "2",
"name": "wikoX"
}]

Table command :

[{
"id": "1",
"phone_id": "1",
"by_who": "michel"
},
{
"id": "2",
"phone_id": "2",
"by_who": "jean"
}
]

On these two tables, I have a cardinality between phone.id and command.phone_id. I can generate it easily with the same_as functionality of your generators.

What I would like now is to generate the difference between the number of iphone and wiko commanded. In an "usual" database the number of row with an iphone should be way larger than the wiko.

More generally, is it possible to change the distribution function of a same_as column from UNIFORM to LOGNORMAL (it just an example).

Thank you for your understanding, you have my start for your great work 👍
