海外TECH	DEV Community	Fast Reads Unleashed: Performance Analysis of AWS GraphQL, DynamoDB, and Redis Cache	https://dev.to/manojlingala/fast-reads-unleashed-performance-analysis-of-aws-graphql-dynamodb-and-redis-cache-1i5a	Fast Reads Unleashed Performance Analysis of AWS GraphQL DynamoDB and Redis CacheIn this article we analyze read performance benchmark results for a selection of AWS services such as GraphQL with AppSync and Lambda Redis Cache using Amazon ElastiCache and DynamoDB in addition to their combined usage We focus on a real world scenario involving a financial institution that handles transactions per second for processing stock market data This examination will help us to better understand the performance characteristics of each service and their combinations allowing to optimize the applications in data intensive industries effectively ScenarioAvg Response TimeRequests per secondLatency th percentile GraphQL with AWS AppSync and Lambda ms msDynamoDB ms msRedis Cache with Amazon ElastiCache ms msGraphQL with AppSync Lambda and DynamoDB ms msGraphQL with AppSync Lambda and Redis Cache ms msDynamoDB with Redis Cache ms msGraphQL AppSync Lambda DynamoDB Redis ms msAvg Response Time Request Per Second Latency th Percentile Based on the benchmark metrics we can conclude the following GraphQL with AWS AppSync and Lambda provides a flexible and powerful solution but has higher latency compared to other services DynamoDB has low latency and excellent read performance making it suitable for applications requiring high throughput and quick access to data Redis Cache with Amazon ElastiCache provides the fastest response times and is ideal for caching frequently accessed data to reduce latency The combination of all services GraphQL with AppSync Lambda DynamoDB and Redis Cache offers a balanced solution with improved performance compared to using only GraphQL with AppSync and Lambda However it still has higher latency compared to using DynamoDB or Redis Cache individually The discrepancy between latency and average response time in the benchmark results is due to the nature of these two performance metrics Here s a brief explanation of both Latency Latency refers to the time it takes for a request to travel from the sender to the receiver and for the receiver to process that request In the context of the benchmark results latency is measured at the th percentile which means that of the requests have a latency equal to or lower than the specified value In other words only of the requests experience higher latency The th percentile latency is often used as a performance indicator to understand the behavior of a system under high load or when dealing with occasional slow requests Average Response Time The average response time is the arithmetic mean of the response times for all requests made during the benchmark It represents the average time taken by the system to process a request and return a response This metric is sensitive to outliers meaning that even a few extremely slow requests can significantly increase the average response time When designing your application architecture it is essential to consider these metrics and tailor the solution to your specific use case Balancing the trade offs between flexibility performance and scalability will result in an optimized solution for your real world application Dear readers if you require more detailed information about each service discussed in this article please feel free to leave a comment below Your feedback is highly appreciated as it will help us improve the quality of our content By sharing our knowledge and assisting each other we can continue to expand our understanding of these technologies and contribute to the growth of the tech community Together we can learn and innovate more effectively	2023-03-25 08:27:30

Here's a new one	https://dev.to/fayaz/my-last-project-i-launched-on-devto-got-acquired-heres-a-new-one-5158	My last project I launched on Dev to got acquired Here x s a new oneI had made and launched fluenticons last year and it got acquired So today I am launching a new one Let s see if the magic works for this too Introducing PostPerfect Improve your tweets right from Twitter I am launching it on Producthunt do check it out and upvote leave a comment if you like it It is built with Vue Vite Crxjs building a chrome extension was quite challenging for me but this was such an interesting product to buildBeen using ChatGPT for everything and I finally thought of building something with it I will keep building more things over time	2023-03-25 08:24:31
