makpar-innovation-laboratory

innoldb

A simple Object-Relation-Mapping for a serverless AWS Quantum Ledger Database backend, and a command line utility for querying tables on those ledgers.

NOTE: The user or process using this library must have an IAM policy that allows access to QLDB.

ORM

The idea behind the ORM is to map document fields to native Python object attributes, so that document values can be accessed by traversing the object property tree.

CRUD OPERATIONS

from innoldb.qldb import Document

# Create a document on `my_table` table.
document = Document('my_table')
document.field = {
  'nested_data': {
    'array': ['colllection', 'of', 'things']
  }
}
document.save()

from innoldb.qldb import Document

# Load a document from `my_table` table.
document = Document('my_table', id="123456")
for val in document.field.nested_data.array:
  print(val)

Queries

from innoldb.qldb import Query

query = Query('my-table').find_by(field_name='field value')
for document in query:
  print(f'Document({document.id}).field_name = {document.field_name}')
