Hi <@U0EC2UPDF>in the future we will be able to create your own ColumnType?

What is preventing you from doing it right now?

right now, basically all implementation of ColumnTypes class is final (in my case, I want to work with a Blob)

You could delegate to a BlobColumnType:
```
class MyBlobColumnType : IColumnType by BlobColumnType() {
    
}
```

wow, tkx

The approach that I'm using is this: <https://github.com/DevSrSouza/KotlinBukkitAPI/blob/master/exposed/src/main/kotlin/br/com/devsrsouza/kotlinbukkitapi/exposed/delegate/Item.kt>

There is `ColumnWithTransform` which accepts two lambdas to convert values to and from a database. Like:
```
class FooEntity() : IntEntity {

   var offlinePlayer = FooTable.playerId.transform({ it.uniqueId }, { offlinePlayer(it) })
}
```

I was think in ask exactly about it, this is a better approach than mine, tkx again

The main problem is the lack of documentation, but we plan to improve it in the near future.
