unwrapInternalSchema

public Schema<?> unwrapInternalSchema(byte[] schemaVersion)

Get a specific schema version, fetching from the Registry if it is not loaded yet. This method is not intended to be used by applications.

Parameters:

schemaVersion - the version

Returns:

the Schema at the specific version

See Also:

• atSchemaVersion(byte[])

fetchSchemaIfNeeded

public void fetchSchemaIfNeeded(SchemaVersion schemaVersion)

It may happen that the schema is not loaded but we need it, for instance in order to call getSchemaInfo() We cannot call this method in getSchemaInfo, because getSchemaInfo is called in many places and we will introduce lots of deadlocks.

Throws:

SchemaSerializationException

toString
