Astra is a cloud-native search and analytics engine for log, trace, and audit data. It is designed to be easy to operate, 
cost-effective, and scale to petabytes of data.

https://slackhq.github.io/astra/

## 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](https://github.com/slackhq/slack-astra-app).
- 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.
