Hi,
Thank you for the great work on Beam. I'm using the golang sdk and hoping
someone might be able to help with defining a customer coder for a type.
I have a type like this:
type Execer struct {
Query string `json:"query,omitempty"`
Args []interface{} `json:"args,omitempty"`
}
Where each element in Args implements `driver.Valuer`.
When trying to run with this as an element of a PCollection I get:
panic: unable to encode type: interface {}
My guess is that I need to define an encode/decode method for the type, but
I'm not sure what interface it should implement. Any direction would be
appreciated.
