How Opensearch Works

Opensearch operates by indexing data in a manner optimized for search and analysis. Data is ingested into an index from various sources such as logs, metrics, and databases. Once ingested, this data can be queried and analyzed using the Opensearch query language, providing users with quick and efficient access to needed information.

Data Ingestion

Data ingestion is the process of taking raw data and indexing it so that it can be searched and analyzed. Opensearch supports a variety of ingestion methods:

  • API Ingestion: Data can be sent directly to Opensearch using its RESTful API.
  • Log Shipping: Tools like Logstash, Filebeat, and Fluentd can ship logs from source systems to Opensearch.
  • Stream Processing: Integrations with data streaming platforms like Apache Kafka allow for real-time data ingestion.

Searching

Opensearch’s powerful query capabilities allow users to perform complex searches on indexed data. The RESTful API facilitates queries and provides instant access to the data, enabling immediate analysis and insights.

Visualization with Opensearch Dashboards

Opensearch Dashboards is an integral part of the Opensearch suite. It allows users to create, visualize, and explore their data using charts, graphs, and other visual aids. This interactivity makes it possible to uncover trends, identify anomalies, and derive actionable insights effectively.

Comparing Opensearch with Other Tools

Opensearch, though highly capable, is not the sole player in the world of search and analytic solutions. Below, we compare Opensearch with other popular tools in the market:

Opensearch vs. Elasticsearch

Elasticsearch is the precursor to Opensearch and often considered the industry standard for search and analytics. The main differences lie in:

  • Licensing: Elasticsearch moved from an open-source license to a more restrictive SSPL license, whereas Opensearch remains under the open-source Apache 2.0 license.
  • Community: Opensearch has a vibrant community-driven development model.
  • Features: While both tools offer similar core functionalities, Opensearch has some distinct plugins and features that are community-developed.

Opensearch vs. Splunk

Splunk is another major player in the data analytics space.

  • Cost: Opensearch is open-source and thus free, whereas Splunk can be quite costly with its commercial software licensing model.
  • Open Ecosystem: Opensearch offers more flexibility thanks to its open-source nature.
  • Functionality: Splunk provides robust enterprise features, but Opensearch is catching up rapidly due to the active community contributions.

Opensearch vs. Apache Solr

Apache Solr is another open-source search platform.

  • Core Technology: Both Solr and Opensearch are based on Lucene, but Opensearch extends its capabilities with more modern features and a comprehensive analytics suite.
  • Ease of Use: Opensearch is considered more user-friendly with better out-of-the-box analytics and visualization tools.

Opensearch vs. Datadog

Datadog is a comprehensive monitoring and analytics platform.

  • Specialization: Datadog is more specialized for monitoring infrastructures and applications.
  • Cost: Opensearch remains a cost-effective solution being an open-source tool.
  • Flexibility: Opensearch offers greater flexibility in terms of customization.
