Access local dynamodb how to#

Once I had implemented all DynamoDB manipulations and had run the unit tests that everything is working properly using the local DynamoDB Docker container instance I tried the unit tests with real AWS DynamoDB profile. batch_writer () as batch : for user_id, email, first_name, last_name, hashed_password in reader : batch. reader ( csvfile, delimiter = ' ' ) with table. With open ( my_csv_file, 'r' ) as csvfile : reader = csv. You can start the local DynamoDB Docker container using command: I found only one item that worked differently in local DynamoDB compared to real AWS DynamoDB service (more about that later). The local DynamoDB was a positive surprise - all DynamoDB APIs I used (cli, Python/boto3, Clojure/amazonica) worked nicely out of the box.

Therefore I decided to use a local DynamoDB Docker container based development database - and have a nice excuse to learn to use it. Local DynamoDB Docker Container Based Development DatabaseДЇor a small exercise with minimal demo data set the DynamoDB price is almost neglectable, but there there is always the round-trip latency to AWS data center. You can find the project in my Github account. Next IвЂ™ll be using this DynamoDB version of Simple Server to deploy the server to EKS and Fargate and write new blog posts regarding those experiences, so stay tuned.

In this blog post I write about my experiences to manipulate DynamoDB using Clojure and how to use local DynamoDB Docker container instance as a development database. I decided to use AWS DynamoDB nosql database.

First I needed to change the implementation to make the server fully stateless - storing all state outside the server in a real external database. The Simple Server was just a demo application and it simulated database by reading csv files to internal data structures - therefore making the server stateful. I decided to use my Clojure Simple Server exercise as a demo application. I decided to refresh my AWS skills a bit and and compare AWS container services EKS and Fargate and compare their deployment models for Docker containers. IntroductionДЄfter my Five Languages project I was searching something new to learn. Running Clojure unit tests in IntelliJ IDEA / Cursive.
