Customer Service

Sentiment score
6.2
Elastic Search offers expert support and documentation, though response times and communication could improve for some users.
Sentiment score
1.0
Users rarely contact Redis support, but those who do find it knowledgeable, with satisfaction levels ranging from moderate to excellent.
The customer support for Elastic Search is one of the best I have ever tried.
Software Developer at a media company with 10,001+ employees
They have always been really responsible and responsive to my requests.
Security Lead at a tech vendor with 501-1,000 employees
It has been sufficient to visit conferences such as SCALE in Southern California Linux Expo, where Elastic Search has a booth to talk to their staff.
Principal Scientific Computing Software Engineer at a educational organization with 1,001-5,000 employees
 

Scalability Issues

Sentiment score
7.3
Elastic Search is highly scalable, enabling efficient node addition, though sharding, replication, and storage demands require careful management.
Sentiment score
7.7
Redis excels in scalability, efficiently handling large datasets with ease, making it ideal for enterprise-level operations and demands.
I would rate its scalability a ten.
Backend Developer
Since we're on the cloud, whenever we need to upgrade or add resources, they handle everything.
Security Lead at a tech vendor with 501-1,000 employees
We haven't encountered any problems so far, and there is the potential for auto-scaling.
Head of Data Management at Zeno Health
Data migration and changes to application-side configurations are challenging due to the lack of automatic migration tools in a non-clustered legacy system.
Data Engineer at a photography company with 1,001-5,000 employees
 

Stability Issues

Sentiment score
7.7
Elastic Search is stable and reliable, despite some challenges, as proper management ensures performance under varying loads.
Sentiment score
7.7
Redis is stable, reliable under heavy loads, supports high availability, and user ratings reflect strong performance, needing load improvements.
The data transfer sometimes exceeded the bandwidth limits without proper notification, which caused issues.
SOC A2 at Innodata-ISOGEN
The stability of Elasticsearch was very high.
Backend Developer
When you put one keyword, everything related to that keyword in your ecosystem will showcase all the results.
Chief Information Security Officer at CDSL Ventures Limited
Redis is fairly stable.
Data Engineer at a photography company with 1,001-5,000 employees
 

Room For Improvement

Elastic Search needs better security, pricing, machine learning, scalability, ease of use, and support, facing significant user challenges.
Enhancements in documentation, user-friendliness, scalability, security, cloud integration, and support are desired improvements for Redis.
From a technical point of view, there are no significant issues recalled as Elastic Search has been absolutely awesome for this use case and covers 100% of the needs.
Principal Scientific Computing Software Engineer at a educational organization with 1,001-5,000 employees
If I need to parse one million records saved into Elastic Search, it becomes a nightmare because I need to do the pagination, and it is very problematic in that regard.
Lead Engineer at Spidersilk
Observability features like search latency, indexing rate, and maybe rejected requests should be added to make the platform more reliable and accessible for everyone.
Senior System Engineer at EPAM Systems
Data persistence and recovery face issues with compatibility across major versions, making upgrades possible but downgrades not active.
Data Engineer at a photography company with 1,001-5,000 employees
 

Setup Cost

Elastic Search's open-source version is free, but enterprises face costs in skills, training, support, and premium features.
Redis's open-source core is cost-effective, but enterprise features require a license; managed services start at $5/month.
On the AWS side, it is very expensive because they charge based on query basis or how much data is transferred in and out, making it very expensive.
Lead Engineer at Spidersilk
Having the hosted solution and not having to pay for essentially a DevOps person on staff to manage makes it affordable.
CTO at a tech services company with 1-10 employees
You can host it on-premises, which would incur zero cost, or take it as a SaaS-based service, where the expenses remain minimal.
Senior Software Engineer at Agoda
Since we use an open-source version of Redis, we do not experience any setup costs or licensing expenses.
Data Engineer at a photography company with 1,001-5,000 employees
 

Valuable Features

Elasticsearch offers real-time monitoring, scalability, and integration with Kibana, enhancing data retrieval, security, customization, and decision-making.
Redis provides fast data access with caching, geolocation, JSON, and supports scalability, high availability, and efficient event-driven applications.
Elastic Search makes handling large data volumes efficient and supports complex search operations.
Software Engineer at Government of India
The most valuable feature of Elasticsearch was the quick search capability, allowing us to search by any criteria needed.
Backend Developer
The speed with which Elastic Search is able to search through all of the documents we place into it is quite remarkable, as we search through 65 billion documents in less than a second in most cases, on a constant consistent basis.
Director, Software Engineering at a tech vendor with 10,001+ employees
It functions similarly to a foundational building block in a larger system, enabling native integration and high functionality in core data processes.
Data Engineer at a photography company with 1,001-5,000 employees

Featured Reviews

Vaibhav Shukla - PeerSpot reviewer
Senior Software Engineer at Agoda
Search performance has transformed large-scale intent discovery and hybrid query handling
While Elastic Search is a good product, I see areas for improvement, particularly regarding the misconception that any amount of data can simply be dumped into Elastic Search. When creating an index, careful consideration of data massaging is essential. Elastic Search stores mappings for various data types, which must remain below a certain threshold to maintain functionality. Users need to throttle the number of fields for searching to avoid overloading the system and ensure that the design of the document is efficient for the Elastic Search index. Additionally, I suggest utilizing ILM periodically throughout the year to manage data shuffling between clusters, preventing hotspots in the distribution of requests across nodes.

Performance shines with seamless session caching and minimal configuration
The best features of Redis, from my personal perspective, are the performance, which is very quick, and it's very simple to implement. Since I started using Redis, I feel that the product is saving me some performance tuning time. It's very easy, I have few parameters to tune, and it seems to have performance without a lot of working on the performance, compared to Cassandra, where you have to configure the memory and many other settings. The integration capability of Redis is excellent. Redis is very affordable because it's free.
