[SOLVED] Corresponding 'Groovy' mapping for required Avro Schema

Corresponding 'Groovy' mapping for required Avro Schema - divolte

I am trying to write a divolte - Groovy mapping for my required Avro Schema, but is throwing errors each time.

Can someone help me with the compatible groovy script mapping ?

Divolte - 0.9.0

Thank you.

Solution

To map Avro 'array' in Groovy mapping DSL, below hack is used. See Groovy mapping for Avro 'array'

map eventParameters().path('$.roleId.*') onto 'roleId'
map eventParameters().path('$.roleName.*') onto 'roleName'

There is no official support for Avro 'enum' field in Groovy mapping DSL. Extend Avro 'enum' field support in mapping DSL
