Each record is accessed with the help of a primary key and key-value pairs, using its proprietary querying layer.Īmazon DynamoDB makes use of a collection of nodes, each of which contains several primary keys, so when a query executes, only those nodes which contain those primary keys get activated and fetch data.
Being a NoSQL database, it stores data in the form of collections, which further contain documents that store data in the form of a key-value pair. It is available as a part of Amazon’s data warehousing suite called Amazon Web Services (AWS). What is Amazon DynamoDB? Image SourceĪmazon DynamoDB is a managed NoSQL database offered by Amazon. It also encrypts messages through SSE as soon as Amazon SQS receives them.įor further information on Amazon SQS, you can check the official website here.
Server-side Encryption: Amazon SQS protects the messages using the AWS-managed Key Management Service (KMS). Message Locking: when Amazon SQS receives a message it gets locked while being processed which allows other computers to process messages simultaneously. Scalability: Amazon SQS decouples the processes that make it easier to scale up sending or receiving rates of messages by simply adding another process. 
The long poll messages wait for upto 20 seconds for the next message to arrive.
Long Polling: Amazon SQS helps in minimizing the cost while receiving messages by reducing extraneous polling. Some of the main features of Amazon SQS are listed below: It further sends server-side encrypted messages, reducing the security risks involved when sending messages between applications running on the cloud. “Standard queues” ensure maximum throughput, best-effort ordering, and at-least-once delivery, whereas the “FIFO queues” ensure that messages are processed exactly once and in the exact order of their arrival. It further eliminates the complexity associated with operating and managing message-oriented middleware and allows developers to focus on differentiating work.Īmazon SQS makes use of two different kinds of message queues, namely Standard and FIFO queues. This way, messages can run and fail independently of each other to avoid slowdowns, disturbance, or system-wide faults within the application.Īmazon SQS allows enterprises to decouple and scale distributed systems, microservices, and serverless applications. 
Step 2: Setting up AWS SQS Event Source using a Lambda FunctionĪmazon SQS is a message queuing service that allows enterprises to run business services and applications in a way that messaging remains independent of the IT infrastructure.
Steps to Migrate Messages from SQS to DynamoDB. Why Migrate Data from Amazon SQS to DynamoDB?. This article aims at providing you with a step-by-step guide to help you connect Amazon SQS to DynamoDB in a hassle-free manner to transfer your data messages efficiently. It stores the messages in the form of queues and makes it possible for the applications to handle the data messages on time. Enterprise applications thus require a complex messaging system to manage such high volumes of data.Īmazon SQS (Simple Queue Service) is one such service that helps enterprises avoid any overloading of their systems and applications. Enterprise applications receive and work with a high volume of messages and notifications, which can put a lot of stress on the system and hence affect the performance negatively.
