A DynamoDB library based on boto3

Project description

# Dynamatic

Dynamatic is a python library for working with DynamoDB. It is NOT an ORM. It sits somewhere between the low-level [boto3]( library (on which Dynamatic is based) and high-level ORMs like [PynamoDB](

## Motivation

First, I was inspired by [this blog post]( which was inspired by [this excellent re:Invent 2018 session by Rick Houlihan]( about how to properly model data in DynamoDB for efficiency and scale.

Second, I did not want an ORM. ORMs like PynamoDB package their own methods of defining object schemas but there are already excellent libraries out there like [Pydantic]( or [Marshmallow]( They also tend to impose traditional relational database patterns (like Active Record) that do not scale well.

Third, boto3 is a great library but its DynamoDB API is painfully low-level and not particularly “Pythonic”. Working with advanced features like [Update Expressions]( and [Projection Expressions]( is complex and unintutive.

So this library aims to be a happy medium: Providing enough abstraction and “developer ergonomics” to get up and running with DynamoDB quickly, while not getting in the way with high-level ORM features.

## Installation

Dynamatic requires Python 3.6 or later. You can install it via pip.

`bash pip install dynamatic `

## Usage

TODO! Documentation and usage examples coming soon!
