Its primary goal is to be cost-efficient, easy to operate, and capable of scaling to manage massive datasets, potentially reaching petabyte levels. Astra stands out by offering several advanced features that are streamlined for modern data demands.

Key Goals of Astra

Native Support for Logs, Traces, and Audits: Astra is tailored to support key data use cases such as logs, traces, and audits, making it a go-to tool for in-depth data analysis.
Prioritization of Recent Data: The platform efficiently prioritizes the ingestion of recent data, ensuring data relevance and prompt accessibility for users.
Full-Text Search Capability: Astra enables comprehensive full-text searches, allowing users to query and retrieve data with ease.
Kubernetes Integration: With first-class Kubernetes support, Astra ensures that its deployment and operation are seamless and efficient across various environments.
Autoscaling Capabilities: It automatically scales its ingest and query capacities based on workload demands, ensuring optimal performance without manual intervention.
Coordination-Free Ingestion: The architecture is designed so that the failure of a single node does not impact the data ingestion process, enhancing system resilience.

Opensearch Replacement: Astra can serve as a drop-in alternative for most log use cases where Opensearch is utilized.
Multi-Cloud Operation: The platform is versatile, operable across various cloud providers.

What Astra Does Not Aim For

While Astra is powerful, there are certain areas it does not focus on:

General-Purpose Searches: It is not designed for generic search cases such as those required by eCommerce platforms.
Document Mutability: Records in Astra are append-only, meaning they are not mutable once ingested.
Multiple Storage Engines Support: Astra is built specifically around Lucene and does not support other storage engines.
JVM Version Support: Astra supports only the current long-term supported (LTS) version of the Java Virtual Machine (JVM).
Multiple Lucene Versions: It retains compatibility with a specific version of Lucene, enhancing stability.
