Does anyone know if you can lazy load columns in exposed? I tried googling but wasn’t able to find any solid answers
I’m having an issue with having a huge blob as a column so it makes loading a ton of rows really slow

05/05/2022, 9:23 PMhmm looking now, I realize that the underlying column was actually set as ColumnType()
Untitled.cpp
I was doing something like this
Copy code
override fun readObject(rs: ResultSet, index: Int): Any? {
val value = super.readObject(rs, index)
return if (eagerLoading && value != null) {
valueFromDB(value)
} else {
value
}
}I took some inspiration from the
TextColumnType()h
