Astra

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.

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.
