Quickwit is a search-engine-for-logs that decouples compute and storage. Indexes live on S3 (or any S3-compatible store); searcher nodes are stateless and horizontally scalable. OpenTelemetry-native ingest for both logs and traces, and a Jaeger-compatible UI.
Pick it if: you want Elasticsearch-style full-text search semantics without the JVM, the hot/cold tier complexity, or the cluster-state pain. Excellent fit if your workload is “search rarely, store forever cheaply.”
Skip it if: you need metrics in the same backend (it is logs+traces only) or you need rich aggregations and visualizations beyond what its built-in UI plus Grafana plugin provide. Also note Quickwit was acquired by Datadog in 2024 — open development continues but governance is single-vendor.
Deployment: single Rust binary or container; Helm chart for k8s. Backed by any S3-compatible store. Operationally lighter than OpenSearch by a wide margin.
