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.
