    The data read from the database by ORM.

    The data read from the database by ORM. Later this should be replaceable by a cursor

    This is just for the 'numeric keys' story

    So important features:*

    • We need to process one to many tables and their children sensibly using the next mechanism
    • That means we will process all the things for my id, and then tell the children The data is sorted by id. Children are sorted by child Id Note that we need the id to by ordered... ANd that's awkward because we don't know how big the composible key is... suppose we have Keys1(a), Keys2(a,b), Keys3(a,b,c)... ah do we actually need the id or can we go flyweight?

    The data in the database is based on tables The data we want in our json or objects is based on an objectgraph There has to be a mapping between the data in the database and the object graph: this is it

    The data in the database is based on tables The data we want in our json or objects is based on an objectgraph There has to be a mapping between the data in the database and the object graph: this is it

    Example: We have a schema: main: key1 table1/field1 key2 table2/field1 child: childKey1 table1/field2 As can be seen there isn't a simple mapping

    This heavily uses type classes, so you can use your own (perhaps existing) schema object. SchemaMapKey[Schema] -> This is how we know what keys exist and what children exist.

    Utility putJson: Very useful if you are using APIs because it writes to an outputstream and is much less garbage/memory intensive than turning to a string first toJson: Nicer interface than putJson

    Debugging: prettyPrint is really helpful for understanding the schema. It is intended for use in tests printArray prints the array of data retrieved from FastOrm in a way helpful for tests

    THere is a schema of type Schema.

    THere is a schema of type Schema. Schema is not the data, is the structure of the data

    The type parameter is the type of the data in the field that the schema is pointing to. This is used for things like 'getting from database' and 'putting in json'.

    Because schemas hold other schemas, and I am not sure how to handle the schema object itself from a [T] perspective there is a fake T called Placeholder.

    The journey of data seems to be

    The journey of data seems to be

    Put into temporary tables Read into memory Transform into a 'thing. Could be a domain object, but usually just seem to want to transform it into list/map/primitive The OrmKeys story is about how to turn it list/map/primitive

    Now we tried the arrays story, and it looks too hard for now. Basically it's a great future optimisation, but too brittle at this stage. The arrays story says 'really efficient/read straight from cursor with no intermediate into the list/map/primitive recognising that the list/map/primitive has a different (configurable) structure.

    So can I do something around Tagless Interpreters to walk the object graph in the raw data. Reasons for doing this including debugging/tracing/documentation/understanding
