Notable Changes in Recent Releases of Elasticsearch


In the dynamic landscape of Elasticsearch, staying updated with the latest releases is crucial for optimizing performance and leveraging new features. In this article, we’ll delve into the notable changes in recent releases of Elasticsearch, highlighting version upgrades, release dates, and key improvements. Whether you’re a seasoned Elasticsearch user or just getting started, understanding these updates can enhance your Elasticsearch experience.


Notable Changes in Recent Releases in Elasticsearch:

Elasticsearch, known for its robust search and analytics capabilities, continues to evolve with each new release. Let’s explore some of the significant changes:


1. Elasticsearch Version 8:

As of the latest updates, Elasticsearch version 8 introduces several enhancements aimed at improving scalability, resilience, and security. This includes optimizations in indexing and search performance, enhancements in data node architecture, and advancements in security features such as role-based access control (RBAC) and encryption.

2. Versions of Elasticsearch:

Elasticsearch offers a range of versions catering to diverse user needs and preferences. From version 6.x, which introduced significant improvements in data ingestion and management, to the latest 8.x series focusing on scalability and security, users have access to a continuum of features and functionalities.


3. Upgrading to the Latest Version:

For users looking to upgrade to the latest version of Elasticsearch, thorough planning and testing are essential. The Elasticsearch documentation provides detailed guidance on the upgrade process, ensuring a smooth transition while minimizing downtime and potential disruptions to operations.


4. Latest Version of Elasticsearch 7:

Elasticsearch 7.x series remains a popular choice for many users, offering a balance of stability and modern features. The latest version within this series introduces enhancements in search relevancy, improvements in index management, and optimizations in resource utilization, catering to diverse use cases and workloads.


5. Release Dates:

Elasticsearch 7 was released on April 10, 2019, marking a significant milestone in the evolution of the platform. Since then, subsequent updates and patches have been released regularly, addressing bugs, introducing new features, and improving overall performance.


6. Difference Between Elasticsearch 9200 and 9300:

Elasticsearch ports 9200 and 9300 are commonly used for HTTP and transport communication, respectively. While both serve similar purposes, port 9300 is typically used for internal node-to-node communication, whereas port 9200 facilitates client communication via HTTP requests.


7. New Name for Elasticsearch:

The rebranding of Elasticsearch to the “Elastic Stack” in recent years reflects its evolution into a comprehensive suite of tools, including Elasticsearch, Kibana, Beats, and Logstash. This change underscores the platform’s versatility and expanded capabilities beyond traditional search and analytics.


8. Updating Data in Elasticsearch:

Elasticsearch provides various mechanisms for updating data, including scripted updates, partial updates using the Update API, and reindexing strategies. These approaches allow users to modify existing documents, incorporate new data, and maintain data integrity within Elasticsearch indices.


9. Changing Type in Elasticsearch:

Although Elasticsearch originally supported multiple types within an index, it has deprecated this concept in favor of a single type per index model. Users transitioning from earlier versions can leverage reindexing tools and mappings to migrate data and adapt to the new paradigm seamlessly.


10. How Update Works in Elasticsearch:

Elasticsearch’s Update API enables users to modify existing documents by specifying the document ID and desired changes. Under the hood, Elasticsearch retrieves the document, applies the modifications, and reindexes the updated document, ensuring consistency and reliability.
