Re: [DISCUSS] FIP-16: auto-increment column

[Yang Wang]

Hi Cheng,

Thank you for driving this FIP. I think it is a nice and important feature
for many real-world business scenarios, and the overall design makes sense
to me. I have just one small question:
Regarding the client-side API design:
```
Schema.newBuilder()
        .column("uid", DataTypes.STRING())
        .column("uid_int64", DataTypes.BIGINT())
        .enableAutoIncrement()
        .primaryKey("uid")
        .build();
```
If there is more than one column with INT or BIGINT type, which one would
be the auto-increment column?

Best regards,
Yang
