DynamoDB Pros & Cons |
https://dev.to/roy8/dynamodb-pros-cons-k2a
|
DynamoDB Pros amp Cons What is AWS DynamoDB AWS DynamoDB is a fast scalable and fully managed NoSQL database service It provides fast and predictable performance with seamless scalability DynamoDB enables you to offload the administrative burden of operating and scaling a highly available database It also provides consistent performance and availability at any scale DynamoDB Advantages PerformanceOne of the main advantages of DynamoDB over traditional relational databases is its performance DynamoDB is designed to offer fast and predictable performance at any scale It uses a unique partitioning scheme that allows it to distribute data across multiple servers while maintaining low latency and high throughput CapacityDynamoDB uses adaptive capacity to automatically adjust capacity in response to changing traffic patterns so you never have to worry about over provisioning or under provisioning your database ScalabilityDynamoDB scales horizontally by adding more servers as needed to handle increased traffic It also scales vertically by adding more capacity to individual servers This allows DynamoDB to handle sudden spikes in traffic without sacrificing performance or availability AvailabilityDynamoDB is also a highly available and fault tolerant database service It uses multiple Availability Zones AZs to replicate the data across multiple servers in different geographic regions This ensures that your data is always available even if one or more AZs goes down Fault toleranceDynamoDB automatically fails over to a standby replica in another AZ if the primary replica becomes unavailable Fully ManagedDynamoDB is a fully managed service which means that Amazon takes care of all the administrative tasks associated with running a NoSQL database This includes patching backing up monitoring and scaling the database This frees up your time so you can focus on developing your applications instead of worrying about managing the infrastructure Security and complianceDynamoDB has encryption at rest and in transit DynamoDB encrypts your data at rest using server side encryption with an AWS Key Management Service KMS master key DynamoDB also supports client side encryption which lets you encrypt your data before you send it to DynamoDB AuditingDynamoDB can streams all data changes made to your table which lets you track activity and monitor for suspicious activity You can also use AWS CloudTrail to log all DynamoDB API calls for further auditing DynamoDB DisadvantagesWhile DynamoDB has many benefits such as being highly scalable and offering low latency there are also some disadvantages to using this service Expensive at ScaleDynamoDB can be more expensive than other database solutions especially when you need to scale The reason for this is that DynamoDB is a managed service which means that AWS takes care of all the underlying infrastructure and management for you This is great if you re not familiar with AWS or if you don t want to worry about managing your own database but it comes at a cost When you need to scale DynamoDB you re essentially paying for AWS to do all the work for you which can add up quickly NoSQL DatabaseDynamoDB is not a good choice for workloads that require a relational database structure This is because DynamoDB is a NoSQL database which means that it does not support the relational database model In addition DynamoDB does not support foreign keys which are necessary for defining relationships between tables in a relational database As a result DynamoDB is not suitable for workloads that require a complex relational database structure Data ConsistencyDynamoDB is not ACID compliant and does not support transactions that span multiple items or tables This makes it an unsuitable choice for workloads that require a high level of data consistency such as financial transactions Complex QueriesDynamoDB s lack of query optimization can make it difficult to execute complex queries efficiently For example a query that requires a full table scan can be very slow Additionally DynamoDB does not support indexing so it can be difficult to find specific items in a large table In conclusion DynamoDB is a great tool for those who need a powerful database solution However it does have its drawbacks If you re looking for a lighthearted and witty take on the pros and cons of DynamoDB this is the article for you Check out our website for more information on what we re up to Join the discussion in our Discord channel and help us shape the future of the project Test your API for free now at BLST |

How to use TypeScript with React |
https://dev.to/omerwow/how-to-use-typescript-with-react-mn9
|
How to use TypeScript with React Why TypeScript I have another article that explains a lot about TypeScript what it is and how and why you should use it You re welcome to read about it here In a nutshell the benefits of using TypeScript include Catching errors early in the development process Making code easier to understand and maintain Providing a better development experience with features like autocompletion and type checking Getting startedTo create a new React application with TypeScript use the following command npx create react app my app template typescriptThat s it the Create React App CLI will create a new app with TypeScript configured properly and you can get started right away If however you have an existing React app that you want to convert to TypeScript you re going to need to do a few extra steps Don t worry though it s pretty simple First install TypeScript and other required packages npm install save typescript types node types react types react dom types jestNow rename all js files to tsx files and make sure to restart your dev server before continuing Also a restart to your code editor IDE may be needed or helpful as well That s pretty much it Be aware that enabling TypeScript in an existing project can introduce or uncover some errors This is usually not a big deal and may even be pretty helpful and help you solve a few bugs You re going to need to deal with them before continuing development Now that we have a working TypeScript React app we can start utilizing TypeScript to improve our development Writing tsx filesWe ll start with a simple React component that renders a header Then we ll use TypeScript to add types and type safety to the component Finally we ll compile the TypeScript code to JavaScript and run the app First let s create a simple React component that renders a header import React from react const Header gt return lt header gt lt h gt Hello world lt h gt lt header gt export default Header This Header component doesn t do much yet it just renders a header element with the text Hello world We can write this component in TypeScript or JavaScript For this example we ll write it in TypeScript Adding Types with TypeScriptNow that we have a basic React component let s add some types with TypeScript We can start by adding types to our props and state import React from react interface HeaderProps message string const Header props HeaderProps gt return lt header gt lt h gt props message lt h gt lt header gt export default Header As you can see we ve added an interface for our props and specified that the message prop is of type string This way if we try to pass anything other than a string to the message prop TypeScript will give us an error We can also add types to our state import React useState from react const count setCount useState lt number gt const Header props HeaderProps gt return lt header gt lt h gt props message lt h gt lt button onClick gt setCount count gt Click me lt button gt lt p gt You ve clicked the button count times lt p gt lt header gt export default Header As you can see we ve added types for our state and specified that the count state variable is of type number This way if we try to set the count state variable to anything other than a number TypeScript will give us an error Exploring the type safety of React event handlersOne of the benefits of using TypeScript with React is that developers can catch errors in their event handlers Event handlers are a way to respond to user input in React applications When an event occurs such as a user clicking a button The compiler will check the type of each parameter in the event handler function and it will also check the return type of the function If there is a mismatch in either of them the compiler will throw an error This means that developers can catch errors in their event handlers before the code runs However there are some potential pitfalls when using TypeScript with React One pitfall is that it is possible to write code that is valid TypeScript but will not compile because of an error in React For example take a look at the following code class MyComponent extends React Component handleClick event MouseEvent do something This code will not compile because of an error in React handleClick must be declared as a static method on MyComponent However this code is valid TypeScript and it will only produce an error when it is compiled with React This means that developers need to be aware of both TypeScript and React when they are writing their code In conclusion TypeScript is a great way to improve your React code It can help you catch errors optimize performance and make your code more readable Plus it s just plain fun to use Star our Github repo and join the discussion in our Discord channel Test your API for free now at BLST |

|
Uber tests train and bus bookings in the UKAs it promised earlier this year Uber is testing bus and train travel options in the UK via a partnership with Berlin based travel platform Omio TechCrunch has reported quot We re excited to launch our new travel offering this summer allowing a seamless door to door travel experience across the UK quot Uber UK general manager Andrew Brem said in a statement nbsp Omio covers over transportation providers in countries It has its own travel app for consumers but has also been developing a business to business API that allows partners to access its ground transport network The company also offers air and ferry travel on its consumer app and website but its primary focus is on train and bus coach travel The company has already partnered with UK s LNER travel site Kayak and others but Uber is its biggest partner so far quot Uber is the first partner that is both at this scale but also the first that gets access to our full ticketing API so you actually are as a customer able to do everything within the Uber app quot Omio CEO and founder Narem Shaam told TechCrunch With access to Omio s API Uber will be able to offer international train travel to UK users right away Trips booked via Uber s app will generate a commission for Omio which it will share with Uber via an undisclosed split Uber is also paying Omio to license its technology nbsp Omio believes that its app has a quot high overlap quot with Uber users and is hoping the deal will increase its UK market penetration Ground transport functionality will be added in phases with a basic feature set launching today and building out over the coming months nbsp |
