Introduction:
In today’s data-driven world, Elasticsearch managing and querying vast amounts of information efficiently is imperative. This is where Elasticsearch comes into play. Elasticsearch, often dubbed as a distributed, RESTful search and analytics engine, offers powerful capabilities in data storage, search, and analysis. ELK Stack Online Training
Understanding Elasticsearch Fundamentals:
- Distributed Nature: Elasticsearch operates in a distributed manner, allowing it to scale horizontally across multiple nodes, ensuring high availability and fault tolerance.
- Document-Oriented: It stores data in the form of documents, which are JSON objects. Each document is stored in an index, which can be thought of as a collection of documents sharing similar characteristics.
- Full-Text Search: One of its core features is its ability to perform full-text search efficiently across large volumes of data. It employs inverted indexes to achieve fast search performance. ELK Stack Training
- Real-Time Data Analysis: Elasticsearch excels in real-time data analysis, making it suitable for various use cases such as log analytics, monitoring, and e-commerce.
Types of APIs in Elasticsearch:
- Document APIs: These APIs enable CRUD (Create, Read, Update, Delete) operations on individual documents. Developers can index, retrieve, update, and delete documents using endpoints such as PUT, GET, POST, and DELETE. ELK Training Online
- Search APIs: Elasticsearch offers powerful search APIs that allow users to execute complex search queries against indexed data. These APIs support features like filtering, aggregations, highlighting, and sorting.
- Cluster APIs: Cluster APIs provide functionalities to manage Elasticsearch clusters. Administrators can use these APIs to monitor cluster health, manage nodes, and perform various administrative tasks.
- Indices APIs: Indices APIs allow users to manage indices in Elasticsearch. These APIs facilitate tasks such as creating, deleting, updating index settings, and managing index aliases. ELK Stack Training in Hyderabad
