schema in JSON format
Create a mutable model based upon the schema.
The model will be created with all mandatory record occurrences and all mandatory field occurrences initialized to default values.
Such a model may be mutated and used to generate updated RecordV2 occurrences for updating purposes.

Returns an immutable, ordered list of record definitions.
There will be at least one.
a list of the record definitions in the schema
A RecordV2 schema.
A schema describes data content in terms of one or more record definitions. A record definition describes the layout of a record and comprises one or more field definitions.
Within the data content there can be multiple occurrences of a record or field described by a single definition. The defined (or allowed, when describing variable numbers) number of occurrences of each definition is referred to as its 'multiplicity'. The multiplicity can be fixed (the item occurs a fixed number of times), or variable (the item occurs from a minimum number of times to a maximum number of times). If a variable field is used it must be the last in a record definition and if a variable record is used it must be the last in the schema definition.
A field may be defined as of type 'string', 'integer' or 'decimal'. A decimal type has a further property of 'scale' which defines the number of digits to the right of the decimal point.
A schema can be obtained from RecordV2DataType.parseSchema or from a SchemaBuilder
