godal/dynamodb

Generic AWS DynamoDB DAO implementation.

Guideline

General

• DAOs must implement IGenericDao.GdaoCreateFilter(string, IGenericBo) FilterOpt.
• Row-mapper's ColumnsList(table string) []string must return all attribute names of specified table's primary key.

Use GenericDaoDynamodb (and godal.IGenericBo) directly

• Define a DAO struct that implements IGenericDao.GdaoCreateFilter(string, IGenericBo) FilterOpt.
• Use a row-mapper whose ColumnsList(table string) []string returns all attribute names of specified table's primary key.

Implement custom DynamoDB business DAOs and BOs

• Define and implement the business DAO (Note: DAOs must implement IGenericDao.GdaoCreateFilter(string, IGenericBo) FilterOpt and its row-mapper's ColumnsList(table string) []string function must return all attribute names of specified table's primary key).
• Define functions to transform godal.IGenericBo to business BO and vice versa.

Optionally, create a helper function to create DAO instances.
