OpenObserve is a single-binary observability platform written in Rust. Data lands in object storage (S3/GCS/MinIO) in columnar format (Parquet). Supports logs, metrics, traces, RUM, session replay.
Pick it if: you want Elasticsearch replacement with dramatic storage-cost reduction, and you like single-binary operations.
Skip it if: you need the vast Elasticsearch ecosystem of integrations.
