All Implemented Interfaces:

Serializable

public class UndefinedSchemaException
extends FaultException

Thrown when the application attempts to use a schema that has not been defined using the NoSQL Database administration interface.

As described in detail under Avro Schemas in the AvroCatalog class documentation, all schemas must be defined using the NoSQL Database administration interface before they can be used to store values.

Depending on the nature of the application, when this exception is thrown the client may wish to

• retry the operation at a later time, if the schema is expected to be available,
• give up and report an error at a higher level so that a human being can be made aware of the need to define the schema.

WARNING: Blocking and internal schema queries may occur frequently if multiple threads repeatedly try to use a schema that is undefined in the store. To avoid this, it is important to delay before retrying an operation using the undefined schema.
