Overview ¶
Package archive implements hot/cold storage tiering for OtelContext. Data older than HOT_RETENTION_DAYS is moved from the relational DB (hot) to zstd-compressed JSONL files on local disk (cold). Cold files are organized as: {cold_path}/{year}/{month}/{day}/{type}.jsonl.zst Each day directory also contains a manifest.json with record counts and checksums.
