In this case, you know and can control the queries you run. In reality, GraphQL is often used for private APIs where you control both the client and the server. This is more of a problem with a public API where users can write arbitrary queries. One of the strengths of GraphQL is that it can handle arbitrary queries more easily by design than REST. Even he recommends against using the two together, mostly because of the way that GraphQL resolvers are often written as sequential independent database calls that can result in excessive database reads.Р”Р„nother potential problem is that DynamoDB works best when you know your access patterns beforehand.

Alex Debrie is a DynamoDB expert who wrote The DynamoDB Book which is a great resource to deeply learn it. GraphQL seems to fit well with relational databases partly because it is assumed by a lot of the documentation, tutorials, and examples. The case against using GraphQL with DynamoDB is a little more nuanced. Future pain that only grows if your application grows.

You are trading the up-front pain of learning something hard to save yourself from future pain. DynamoDB is serverless-friendly by design. Where do you stand up that SQL database? How do you manage connections to it? These things just donРІР‚в„ўt mesh with the serverless model very well. But SQL databases are not the best fit with serverless applications. I agree the learning curve feels very steep. The main objection to DynamoDB is that it is hard to learn, but few people argue about its power. The main objections to DynamoDB and GraphQL Maybe when weРІР‚в„ўre done you might consider giving DynamoDB a second look. To show you what I mean, letРІР‚в„ўs build an API from start to finish - without any heavy Object Relational Mapper (ORM) or GraphQL framework to hide what is really going on. But after learning and using DynamoDB, I see the benefits of it for projects of any scale. That was my assumption, too, and I tried to stick with a SQL database for my serverless apps. ItРІР‚в„ўs often dismissed by folks who consider it only worth the effort РІР‚Сљat scale.РІР‚Сњ The first two are well-loved, but DynamoDB is often misunderstood or actively avoided. var AWS = require('aws-sdk') Р”Вynamodb.Serverless, GraphQL, and DynamoDB are a powerful combination for building websites.

This blog will show how to create a DynamoDB table in your local environment. What about the local environment!? On the SQL side, you can set up the SQL database on your local, how about the DynamoDB? You can reference this blog for how to setup Dynamodb in your local environment. On the SQL database, you or someone need to create a server for the SQL database, you then access the SQL database on that server by SQL query, but on the other hand, AWS will be managing the server for this NoSQL, serverless DynamoDB database. You can create an AWS account then go to the AWS console's DynamoDB section to create a table and add items. AWS DynamoDB is one of the AWS services for the NoSQL database on the cloud.
