The first reason DynamoDB calls are taking long is because the HTTP requests that the AWS SDK is making to DynamoDB is timing out. There are two common ways DynamoDB calls might timeout.

Thus, the next step was to figure out how to handle these timeouts so that our users weren’t being adversely affected by them. We confirmed with Mike Apted that this is a farily normal timeout rate for DynamoDB calls. Roughly 0.00002% of all our DynamoDB calls were timing out.

We observed timeouts across BatchGet, Get, Query, and Update calls. However there were no specific types of calls that were timing out. We used AWS X-Ray to trace the calls and found that the DynamoDB call seemed to be taking abnormally long. We noticed that a certain percentage of our Node.js Lambda function calls were timing out. Let’s start by looking at the issue itself. Hopefully sharing our experience ends up being helpful to other folks. But we recently had to work through this issue. This is a fairly specific issue related to Node.js Lambda functions calling DynamoDB. If you have any doubts, feel free contact me and I will try to resolve it on a personal basis.In this post we are going to look at how to debug DynamoDB timeouts in Serverless apps. Hooray, this way we have successfully connected to Atlas using Node.js. This was the basic setup needed to get Atlas up and running. I leave it up to you to use according to your need. You can take this to the next step by configuring your DB model by creating a "Collection" with various fields and connecting it with the express server.

Run the following code by typing node db.js and you will see Connected to the database in your console. Replace "password" with your user password and also the "dbname" with the name you'd like to have for your database. Copy-paste the following code to db.js.Ĭonsole.error(`Error connecting to the database.
NODE.JS HOW TO CONNECT TO THE LOCAL DYNAMODB DOCUMENTCLIENT INSTALL
Install mongoose in your project by npm install mongoose. Now, its time to create our database connection using mongoose. On clicking, you have to select "Node.js" in the next page and save the connection string provided by Atlas somewhere for further use. To do this, go to the main page of your cluster and click on "Connect" which will give you a modal like this: In this step, we will connect our server to the database. Now, we've all set up done to use it to our Node.js server. Click on Allow access from anywhere which sets it to global access. Upon clicking that, you will be given with the following page. To whitelist your IP address, go to SECURITY > Network Access and click on "Add IP Address". Now, the next step is to Whitelist your IP address so it can recognize your machine for regular access. We will need it later on to create a connection string (URI) of our DB. Fill out the username and password, leaving all settings to default and make sure you remember your credentials. Go to Database access under SECURITY and click on "Add New Database User". Now, its time to add Database User and IP address of your current machine.
Till this step, we have successfully created our Cluster. Step 3: Add User and whitelist IP address We will now look at how to create and configure database collections and integrate it with our express server Come back to the same page once all is finished.
Now, MongoDB will configure and create your cluster and this process will take about 5-10 minutes (pretty long tbh). Name cannot be changed once the cluster is created.Ĭompleting all the above steps is what you need to create a Cluster. If you want to change the name of your Cluster, you have to do it in this step only. Upon selecting those, you can leave all other settings to their default and can go ahead. Here, on this page, you need to select Cloud Provider, and your Region. Upon clicking "Build a cluster", you will be given with the following options: If you have no created clusters, you will see the below page on your dashboard.

After doing all basic registration and setup, it's time to create a Cluster.Īfter Registration/Login and choosing your plan, let's get our Cluster setup done.
There are 3 types to choose from, for testing and learning purpose, "FREE PLAN" will suit your needs perfectly. If you logging in for the first time, you will need to choose a plan for your account. If you already have an account, go ahead. Step 1: Register/Login and create your planĬreate your account at Atlas and register yourself to their service. You can use Atlas for any project which needs to be deployed, whether for development purpose or production environment. In this post, I will tell you how you can connect to MongoDB Atlas, a cloud-based DB service, from your local Node.js / Express.js environment.
