Each query in Elasticsearch is processed on a single thread per shard. Each shard is an instance of a Lucene index, which you can think of as a self-contained search engine that indexes and handles queries for a subset of the data in an Elasticsearch cluster. Each index consists of one or more shards. What are Shards in Elastic search let's understand more about shards Elasticsearch organizes data into indices. We chose to have 3 Master nodes in case when a single Master Node Fails Other Master node will help in those scenarios We chose the M5 Extra Large with an EBS volume of 512GB SSD and 16GB RAM, giving us 1.5TB of ability to store more than 100M data points. We will share how we optimize shards and replicas to achieve better performanceįirst and first, we'd want to describe and share the configuration we chose for Open search on AWS, which included three Master Nodes and three Data Nodes. OpenSearch, like Elasticsearch and Apache Solr, is driven by the Apache Lucene search library. OpenSearch is a highly scalable system for delivering quick access and reaction to massive amounts of data, as well as an integrated visualization tool, OpenSearch Dashboards, that allows users to easily examine their data. OpenSearch is a distributed, open-source search and analytics package that may be used for a variety of applications such as real-time application monitoring, log analytics, and website search. I love and enjoy working on an elastic search I have 6 years of professional experience in software development lifecycle spanning across multiple sectors including Telecommunications, Geospatial, Oil, and Gas with a focus on quality and on-time thanks to Andres Iriarte Hi, I am Birendra Singh I have completed Bachelor in Electronic Engineering. I work at Jobtarget as a data collection and processing specialist, where I spent the majority of my time designing Ingestion Framework and building microservices and scalable architecture on AWS.īirendra Singh (Python Developer | Search Engineer | Data Specialist ) I have a YouTube channel where I teach people about Data Science, Machine Learning, Elastic Search, and Amazon Web Services. I have vast experience designing scalable and high-performance Python software applications.
