 Review comment:
   Can we assert the type to be "Serializer" before casting it, similar to 
below for "Deserializer"?

   Maybe the type here should be just "Object".

   It seems that Table.getCols() is already doing what it's done here. Could 
you please check?

 Review comment:
   Casting is fine, but can we name the variable differently?

 Review comment:
   Not sure if I understand this. Interfaces Serializer and Deserializer are 
independent. While a serde class may implement both, it seem weird to name a 
variable "serializer" and later cast it to Deserializer type.

 Review comment:
   It would be great to cover text/csv as it's also comment, especially for 
testing/poc.
