Frequently asked questions
Is OpenSearch free?
Yes, all its components are under the Apache 2.0 license, including security and alerting.
OpenSearch or Elasticsearch?
They share an origin and many concepts, but have diverged. OpenSearch offers an Apache 2.0 license and included plugins; compare the features you need.
Can I reuse my Elasticsearch knowledge?
Largely: indexes, shards, DSL and mapping remain close. ISM replaces ILM, and you must use the OpenSearch clients.
Do I need Data Prepper?
No: an ingest pipeline is enough for simple transformations. Data Prepper serves heavy processing and OpenTelemetry.
