livedb-dynamodb

DynamoDB adapter for LiveDB.

Operations and metadata are stored in DynamoDB, and snapshot data is stored in S3.

As with livedb-mongo, doc metadata is stored in the main table and operations are stored in TABLE_ops.

Usage

livedb-dynamodb wraps a AWS.DynamoDB and AWS.S3 object from the aws-sdk npm package.

AWS = require("aws-sdk");

var livedbdynamodb = require('livedb-dynamodb');
var dynamodb = livedbdynamodb(new AWS.DynamoDB());
var s3 = livedbdynamodb(new AWS.S3());

var livedb = require('livedb').client(dynamodb, s3, { bucketName: "my-snapshot-bucket" });

Creating Tables

The package includes a small commandline utility to create your DynamoDB tables. (You can create your S3 bucket as usual.)

First, you'll need a aws.json file with your credentials of the form:

{ "accessKeyId": "ACCESS_KEY", "secretAccessKey": "SECRET_ACCESS_KEY", "region": "REGION" }

Where region is us-west-1, etc.

To create tables, run:

node_modules/livedb-dynamodb/bin/init.js

You'll need to specify -t for the table name and your credentials file with -c. You can also specify --local if you have a running instance of [Local DynamoDB] 1. For example:

node_modules/livedb-dynamodb/bin/init.js -t -c credentials.json --local
