# Amazon DynamoDB Accelerator (DAX) Reviews **Vendor:** Amazon Web Services (AWS) **Category:** [Web Server Accelerator Software](https://www.g2.com/categories/web-server-accelerator) **Average Rating:** 4.2/5.0 **Total Reviews:** 18 ## About Amazon DynamoDB Accelerator (DAX) Amazon Relational Database Service (RDS) is a web service that makes it easy to set up, operate, and scale a relational DB in the cloud: Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle, and Microsoft SQL Server. ## Amazon DynamoDB Accelerator (DAX) Reviews ### 1. Must needed NoSQL management tool for DynamoDB **Rating:** 5.0/5.0 stars **Reviewed by:** Adarsh G. | Software Developer, Small-Business (50 or fewer emp.) **Reviewed Date:** April 20, 2022 **What do you like best about Amazon DynamoDB Accelerator (DAX)?** Dynamo itself is amazing but using DAX give us the much needed low latency catching and most importantly it allows easier development of serverless applications. Also, you personally don't have to manage the cache layer so that's amazing. **What do you dislike about Amazon DynamoDB Accelerator (DAX)?** Costing is the only issue I can think of right now but other than that it's just amazing. Just some better pricing may make it the best as it is optimum for small scale projects but in high scale it may cost tons. **What problems is Amazon DynamoDB Accelerator (DAX) solving and how is that benefiting you?** In our company, the project name is ATRIS(Automated Transcript Intelligent and Smart) so all our usage generally includes usage of machine learning models and using the data given as output from those models to process something else. So basically some important use cases for us are: - Latency on accessing data from the database and thus making our API call faster. - The most important use case which saved us a lot of time is storing the pickle data from our models which we generally stored in DB and accessed regularly to train or get some desired output is directly saved on the DAX which makes our application 20 per cent faster. ### 2. Managing caching and invalidating caching is now done automatically through DAX!! **Rating:** 5.0/5.0 stars **Reviewed by:** Jainal G. | Software Development Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** April 20, 2022 **What do you like best about Amazon DynamoDB Accelerator (DAX)?** Well, pretty much everything. Before DAX was introduced I.e before 2017 managing caching, invalidating cache with the right approach without getting those x-cache miss errors was a nightmare for us. Thus when we heard in April, 2017 about DAX getting released which pretty much-managed cache population and invalidation automatically we were so excited, and turns out we stopped getting those x-cache miss errors and was really wonderful for us. **What do you dislike about Amazon DynamoDB Accelerator (DAX)?** Customizing how the cache approaches and having some control on what to cache and add our custom logic on top it is missed as the caching management is handled by DAX which actually okay if you want to leave that hassle and focus on building your application. **What problems is Amazon DynamoDB Accelerator (DAX) solving and how is that benefiting you?** Firstly using DAX didn't required to change our application code (as it is compatible with existing Amazon DynamoDB API Calls) Secondly, we were getting lots of issues in caching population and invalidation and DAX solved all these problems by automating these underlying issues. Thirdly, The query performance increased up to 10x. Finally, Under load conditions, the system can now handle millions of QPS efficiently. ### 3. Super fast and fully managed Dynamo DB **Rating:** 4.0/5.0 stars **Reviewed by:** faizan s. | Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** April 20, 2022 **What do you like best about Amazon DynamoDB Accelerator (DAX)?** DAX is a NoSQL database service that is fully automated. With the introduction of DAX, the speed increases tenfold. It has an in-memory catch system that enhance the speed of the default dynamo DB. **What do you dislike about Amazon DynamoDB Accelerator (DAX)?** While old Dynamo DB has to use an external catching feature the DAX made catching simple. With lower latency and lowering the cost. so all in all I didn't find any thing bad about DAX. **Recommendations to others considering Amazon DynamoDB Accelerator (DAX):** I would say instead of implementing external catching services like elastic search go for DAX it is fast, efficient and inexpensive. **What problems is Amazon DynamoDB Accelerator (DAX) solving and how is that benefiting you?** While working on my startup ATRIS we used to save transcripts of MOM of meetings. We had implemented Dynamodb and had faced some latency issues. We plan to implement elasticache but then we find DAX and it simply works amazing. ### 4. DAX makes DynamoDB one of the best managed NoSQL DB **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Internet | Enterprise (> 1000 emp.) **Reviewed Date:** April 28, 2022 **What do you like best about Amazon DynamoDB Accelerator (DAX)?** Its is self managed and the integration is very simple. It boosts the application performance exponentially by adding cache layer on top of DB. **What do you dislike about Amazon DynamoDB Accelerator (DAX)?** There are additional charges for DAX along with DynamoDB charges. It would have been better if the costs were low for DAX usage. Also DAX is not present in all the AWS regions **What problems is Amazon DynamoDB Accelerator (DAX) solving and how is that benefiting you?** it reduces the latency of the read calls by a large fraction. Also, we don't have to care about the caching implementation on the application end ### 5. DAX has become essential if you are already using Amazon DynamoDB **Rating:** 4.5/5.0 stars **Reviewed by:** Bharat s. | Senior Manager, Information Technology and Services, Enterprise (> 1000 emp.) **Reviewed Date:** October 30, 2019 **What do you like best about Amazon DynamoDB Accelerator (DAX)?** Amazon DynamoDB Accelerator (DAX) is a fully managed, highly available, in-memory cache for DynamoDB that delivers up to a 10x performance improvement. DAX does all the heavy lifting required to add in-memory acceleration to your DynamoDB tables, without requiring developers to manage cache invalidation, data population, or cluster management. Now you can focus on building great applications for your customers without worrying about performance at scale. Just as with DynamoDB, you only pay for the capacity you provision. **What do you dislike about Amazon DynamoDB Accelerator (DAX)?** Nothing to dislike as it gets integrated with the whole AWS ecosystem very coherently. The only thing is the cost factor that you need to factor in before making use of this tool. **What problems is Amazon DynamoDB Accelerator (DAX) solving and how is that benefiting you?** It has improved our cloud-based application's speed and efficiency a lot. Now we are making use of it more and more to get the most out of our Dynamo tables and get the result back as fast as possible. ### 6.
