Why not to use Elasticsearch?

Elasticsearch is an amazing search engine, however there are certain limitations that should be taken into consideration before using.

First, Elasticsearch is not well suited for managing structured data. It is better at searching through unstructured data. Additionally, data size can become an issue when working with large datasets.

This can be alleviated by the use of sharding, but the process does add complexity to the setup. As Elasticsearch is an open-source software, it lacks the enterprise-level support services of many commercial solutions — including managed support and consulting.

Finally, Elasticsearch may not be the best choice for applications that require real time analytics. Depending on the size of the data set and the query requirements, real-time queries can take longer than reasonable due to the need to search through all the stored data.

For these reasons, it is important to consider the needs of your application before deciding to use Elasticsearch. It is a great search tool, but it might not be the best choice in all cases.

What is the disadvantage of Elasticsearch?

Elasticsearch has a few disadvantages that users should be aware of.

First, due to its distributed nature, Elasticsearch has a much steeper learning curve compared to other solutions like SQL databases. This means that it takes more up-front time and effort to understand the architecture and develop effective query requests.

Second, Elasticsearch does not have a fully featured security model like other databases. It is important to secure the cluster correctly with authentication, authorization, and encryption.

Third, Elasticsearch is memory intensive and network intensive. Its performance decreases when queries spread over multiple nodes of a cluster.

Finally, Elasticsearch is not transactional. This means that users should be aware of atomicity and data integrity issues when making changes.

In conclusion, while Elasticsearch offers some performance advantages over SQL databases, it also has a few significant disadvantages that should be kept in mind before deciding to use it.

Is Elasticsearch faster than Postgres?

The short answer is:Yes, Elasticsearch is generally faster than Postgres when it comes to searching, indexing and retrieving data.

The longer explanation is as follows – Elasticsearch is built on Lucene, an open source full-text search library. Elasticsearch is able to take advantage of Lucene’s speed, scalability and flexibility in order to provide millisecond response times and is designed to meet the needs of high-traffic environments.

Elasticsearch is also optimized for heavy read/write operations, making it ideal for large data sets.

In comparison, Postgres is a traditional SQL database with a focus on reliability and data integrity. While it is certainly possible to search for data in Postgres, it is not designed for search operations and can take significantly longer to return results when compared to Elasticsearch.

Therefore, Elasticsearch is generally considered to be much faster than Postgres when performing search and retrieval operations. However, when it comes to read/write operations, Postgres may be a better choice depending on your specific needs.

Is OpenSearch same as Elasticsearch?

No, OpenSearch and Elasticsearch are not the same. OpenSearch is a search and advertising technology developed by Amazon that powers its products and services, and it allows developers to build applications that use Amazon’s search and advertising services.

Elasticsearch, on the other hand, is an open source search engine based on Apache Lucene. It is written in Java and provides advanced features such as full-text search, analytics, and data storage. Unlike OpenSearch, Elasticsearch is distributed, which means the data can be stored in multiple nodes and can be queried from all the nodes.

Additionally, Elasticsearch provides scalability and allows applications to manage large amounts of data.

Do I need to pay for Elasticsearch?
