Introduction to Astralog
Astralog is a distributed, high-throughput event ingestion engine designed for modern, high-scale architectures.
It bridges the gap between distributed applications (Microservices, Serverless, Edge Functions) and high-performance analytical storage (ClickHouse) by introducing an intelligent, S3-backed “Shock Absorber” layer.
The Ingestion Problem
As systems scale, logging becomes a massive bottleneck. Sending events directly to a traditional database leads to:
- Write Saturation: Databases struggle with thousands of small, concurrent write operations.
- Latency Spikes: Your application waits for the database to acknowledge each event, slowing down the end-user experience.
- Data Loss: If the database goes down or slows down, events are dropped or buffers overflow.
- Prohibitive Costs: Traditional observability platforms charge high premiums for ingestion and storage.
The Astralog Solution
Astralog solves these issues by decoupling Ingestion from Storage:
- Non-Blocking Ingestion: Our native SDKs buffer events in-memory and send them in bulk.
- The Shock Absorber: The Astralog engine receives traffic and immediately persists it to S3-compatible storage as compressed GZIP objects. This ensures 99.999% durability at near-zero latency.
- Analytical Power: A background worker syncs the data into ClickHouse using large, optimized bulk inserts, enabling sub-millisecond SQL queries on millions of rows.
Why use Astralog?
| Feature | The Astralog Advantage |
|---|---|
| Performance | Ingest 500,000+ events per second on a single node. |
| Durability | Events are safe in S3 before they ever reach the database. |
| Cost | 9.3x average compression. 10x cheaper than enterprise tools. |
| Simplicity | One Go binary. One S3 bucket. One ClickHouse table. |
| Querying | Pure ClickHouse SQL. No complex new languages to learn. |
Who is it for?
- SaaS Founders: Who need multi-tenant logging for their customers.
- DevOps Engineers: Who are tired of managing heavy ELK clusters.
- Platform Teams: Looking to reduce observability bills by 90% using their own cloud infrastructure.
