Overview

Package eav contains the logic for the Entity-Attribute-Value pattern (WIP).

To use this library with additional columns in the EAV tables you must run from the tools folder first `tableToStruct` and then build the program `eavToStruct` and run it.

Definition of attribute backend, source, and frontend models:

- Backend: Provides hooks before and after save, load, and delete operations with an attribute value. - Source: Provides option values and labels for select and multi-select attributes. - Frontend: Prepares an attribute value for rendering on the storefront and admin backend.

Backend models can be an alternative to an observer; for example, when you have to do something that depends on an attribute value when an entity is saved.

TODO(CSC): idea to import data quickly: see Entity-Attribute-Value_(EAV)_The_Antipattern_Too_Great_to_Give_Up_-__Andy_Novick_2016-03-19.pdf Break it down to single partition operations • SQLCLR proc breaks the file by attribute_id • SEND attribute_id’s data to a Service Broker QUEUE • Each task is working on ONE attribute_id – That’s one HOBT / Partition • Run 1-2 tasks per core CSC: in our case run a pool goroutines to work on the attribute IDs or for each attribute_id a dedicated goroutine (maybe code generated)

	ByCode(code string) (AttributeIndex, error)
}

AttributeGetter implements functions on how to retrieve directly a certain attribute. This interface is used in concrete attribute models by generated code. The logic behind this interface is to provide a fast access to the AttributeIndex. We will use as key the id int64 or code string which will then map to the value of an AttributeIndex.

	GetOptionText(value string) string
	// Config to configure the current instance
	Config(...AttributeSourceConfig) AttributeSourceModeller
}

AttributeSourceModeller interface implements the functions needed to retrieve data from a source model @see magento2/site/app/code/Magento/Eav/Model/Entity/Attribute/Source/SourceInterface.php and its abstract class plus other default implementations. Refers to tables eav_attribute_option and eav_attribute_option_value OR other tables. @todo

	IsRequired() bool
	IsUserDefined() bool
	DefaultValue() string
	IsUnique() bool
	Note() string
}

Attributer defines the minimal requirements for one attribute. The interface relates to the table eav_attribute. Developers can even extend this table with additional columns. Additional columns will result into more generated functions. Even other EAV entities can embed this interface to extend an attribute. For example the customer attributes extends this interface two times. The column of func AttributeModel() has been removed because it is not used and misplaced in the eav_attribute table. This interface can be extended to more than 40 functions which is of course not idiomatic but for generated code it provides the best flexibility to extend with other custom structs. @see magento2/site/app/code/Magento/Eav/Model/Entity/Attribute/AbstractAttribute.php @see magento2/site/app/code/Magento/Eav/Api/Data/AttributeInterface.php
