- Reproducible pipelines
- Custom index building
- Research grade tools
Quickwit
Quickwit is an open-source, cloud-native search engine optimized for log management, distributed tracing and analytics on large datasets stored in object storage. It is designed to be cost efficient at scale.
- Search directly on object storage
- Optimized for logs and traces
- Decoupled compute and storage
- Elasticsearch-compatible API
