Goals

Native support for log, trace, audit use cases.
Aggressively prioritize ingest of recent data over older data.
Full-text search capability.
First-class Kubernetes support for all components.
Autoscaling of ingest and query capacity.
Coordination free ingestion, so failure of a single node does not impact ingestion.
Works out of the box with sensible defaults.
Designed for zero data loss.
First-class Grafana support with accompanying plugin.
Built-in multi-tenancy, supporting several small use-cases on a single cluster.
Supports the majority of Apache Lucene features.
Drop-in replacement for most Opensearch log use cases.
Operate with multiple cloud providers.

Non-Goals

General-purpose search cases, such as for an ecommerce site.
Document mutability - records are expected to be append only.
Additional storage engines other than Lucene.
Support for JVM versions other than the current LTS.
Supporting multiple Lucene versions.
