PostgreSQL and Elastic Search compete in the database management systems category. PostgreSQL seems to have the upper hand due to its solid support in production environments with ACID compliance and reliability, whereas Elastic Search stands out for its advanced search capabilities, suitable for handling large volumes of unstructured data.
Features: PostgreSQL provides robust spatial support perfect for GIS applications, extensive functions including JSONB, full-text search, partitioning, and built-in scalability. It is well-regarded for reliability, performance, and strong community support. Elastic Search offers excellent data indexing and search capabilities with near real-time processing, ideal for unstructured data. Its integration with tools like Kibana enhances usability, providing efficient search experiences and insightful analytics.
Room for Improvement: PostgreSQL could enhance user-friendliness, query profiling, and native multi-master replication support. Improvements in parallel query execution and monitoring are also beneficial. Elastic Search could improve setting up semantic search, offering better dashboards in Kibana and stronger vector database capabilities. Enhanced user documentation and wider integration capabilities would broaden market appeal.
Ease of Deployment and Customer Service: PostgreSQL supports various deployment options including on-premises and cloud environments, relying on a strong community and third-party services for support. Elastic Search offers similar deployment flexibility with community and third-party support. Enterprise users often seek commercial support due to its complex nature, with Elastic Search users finding commercial assistance more beneficial for specialized needs.
Pricing and ROI: PostgreSQL is cost-effective as an open-source solution, offering immediate ROI with no licensing fees, with minimal setup costs primarily for expertise and hardware. Elastic Search, while affordable as an open-source solution, can become costly with enterprise features and commercial support due to its node-based pricing model. It balances this with superior search capabilities, though careful cost management is essential as scalability demands increase.
We have not purchased any licensed products, and our use of Elastic Search is purely open-source, contributing positively to our ROI.
It is stable, and we do not encounter critical issues like server downtime, which could result in data loss.
The main benefits observed from using Elastic Search include improvements in operational efficiency, along with cost, time, and resource savings.
For P1 tickets, they provide very immediate quick responses and join calls to support and troubleshoot the issue accordingly.
The customer support for Elastic Search is one of the best I have ever tried.
They have always been really responsible and responsive to my requests.
If PostgreSQL is hosted on cloud services such as Amazon RDS or Google Cloud SQL, the support is handled by the cloud provider, who provides automated backups, monitoring, infrastructure management, and technical support tickets.
Overall, we have a very small customer service team and a good engineering team with no overburden or bandwidth issues.
We can search through that document quite easily, sometimes in 7 milliseconds, sometimes one or two milliseconds.
Performance tests involving one million requests at once, we encountered issues with shards and nodes not upscaling as needed, leading to crashes and minimal data loss.
I would rate its scalability a ten.
Now, we are doing the same level of transactions in PostgreSQL, around 100,000 transactions, and we are getting good throughput with no latency.
The data transfer sometimes exceeded the bandwidth limits without proper notification, which caused issues.
The stability of Elasticsearch was very high.
When you put one keyword, everything related to that keyword in your ecosystem will showcase all the results.
I have never seen any performance issue in PostgreSQL.
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.
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.
Observability features like search latency, indexing rate, and maybe rejected requests should be added to make the platform more reliable and accessible for everyone.
Query optimization improves slow queries by using proper indexes, avoiding unnecessary joins, and using EXPLAIN ANALYZE to inspect query plans.
If I need to increase the dimension to 3,000 or 5,000, that option should be available.
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.
Having the hosted solution and not having to pay for essentially a DevOps person on staff to manage makes it affordable.
You can host it on-premises, which would incur zero cost, or take it as a SaaS-based service, where the expenses remain minimal.
Even with doing 100,000 transactions right now within PostgreSQL, we are happy with PostgreSQL and not seeing that it is expensive or going out of budget.
Elastic Search makes handling large data volumes efficient and supports complex search operations.
The most valuable feature of Elasticsearch was the quick search capability, allowing us to search by any criteria needed.
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.
PostgreSQL improves reliability, performance, and scalability in production. Since it is ACID compliant, it ensures that database transactions are safe and consistent, preventing partial data updates, maintaining data integrity, and allowing multiple users to read or write data simultaneously using MVCC.
The best feature is performance, because of which I decided on PostgreSQL.

Elasticsearch is a prominent open-source search and analytics engine known for its scalability, reliability, and straightforward management. It's a favored choice among enterprises for real-time data search, analysis, and visualization. Open-source Elasticsearch is free, offering a comprehensive feature set and scalability. It allows full control over deployments but requires managing and maintaining the infrastructure. On the other hand, Elastic Cloud provides a managed service with features like automated provisioning, high availability, security, and global reach.
Elasticsearch excels in handling time-sensitive data and complex search requirements across large datasets. Its scalability allows it to handle growing data volumes efficiently, maintaining high performance and fast response times. Integrated with Kibana, Elasticsearch enables powerful data visualization, providing real-time insights crucial for data-driven decision-making.
Elastic Cloud reduces operational overhead and improves scalability and performance, though it comes with associated costs. It is available on your preferred cloud provider — AWS, Azure, or Google Cloud. Customers who want to manage the software themselves, whether on public, private, or hybrid cloud, can download the Elastic Stack.
At its core, Elasticsearch is renowned for its full-text search capabilities, capable of performing complex queries and supporting features like fuzzy matching and auto-complete.
Peer reviews from various professionals highlight its strengths and weaknesses. Pros include its detection and correlation features, flexibility, cloud-readiness, extensibility, and efficient search capabilities. However, users have noted challenges like steep learning curves, data analysis limitations, and integration complexities. The platform is generally viewed as stable and scalable, with varying degrees of satisfaction regarding its usability and feature set.
In summary, Elasticsearch stands out for its high-speed search, scalability, and versatile analytics, making it a go-to solution for organizations managing large datasets. Its adaptability to different enterprise needs, robust community support, and continuous development keep it at the forefront of enterprise search and analytics solutions. However, potential users should be aware of its learning curve and the need for skilled personnel for optimization.
