Hi Team, when I try to update schema, I get this error

{
  "code": 400,
  "error": "Backward incompatible schema <name>. Only allow adding new columns"
}

What is the way to make schema backward compatible and allow updates to schema ?

are you trying to change the schema name, if so, that’s a backward incompatible change

Removing a column, changing data type (int to long is ok, string to int isn’t for example).
