Jul 1, 2025July 2025 monthly summary for quickwit-oss/quickwit: Focused on simplifying OTLP ingestion by removing per-log/trace deduplication and streamlining the parsing path. The change switches OTLP log/trace parsing to return Vec instead of BTreeSet and updates downstream iterators, reducing data manipulation and maintenance burden while preserving correctness. This lays groundwork for more predictable ingestion throughput and easier future enhancements.

Jan 1, 2025January 2025 (2025-01) highlights: licensing modernization, default ingestion v2, and targeted reliability improvements across the repo. Open Source Licensing Modernization relocates AGPLv3 to Apache 2.0, with updated badges, a new NOTICE file, and adjusted headers to reflect Apache 2.0 licensing, reducing legal risk and enabling broader adoption. Ingest V2 is now the default ingestion method, removing the --v2 flag and ingest_v2 from ClientArgs; config and control plane were updated and tests adjusted, simplifying configuration and improving consistency. Date/Time Parsing: removed 2-digit year support in the Java datetime parser to align with the time crate limitations and improve robustness. Ingestion Shard Rate Limiting: enhanced error handling to return 429 When all shards for an index are rate-limited, providing clearer feedback under burst load. Maintenance and Dependency Upgrades, CI, and Observability Enhancements: consolidated maintenance work, including test config improvements, CI license checks, weekly Dependabot, and dependency/observability upgrades (Datadog license file, aws-sdk-s3 pinning to 1.62, and updates to opentelemetry/tracing and related metrics). These changes reduce risk, improve reliability and observability, and position the project for scalable adoption.
