What needs docs
- Docs update needed — #8056:
querier.partition_ring.read_lookback_periodis only in generatedmanifest.md. Add it todocs/sources/tempo/configuration/_index.mdunder querierpartition_ring, and clarify inactive-partition read eligibility indocs/sources/tempo/reference-tempo-architecture/partition-ring.md. - Docs update needed — #8068: TraceQL metrics
target_bytes_per_jobdefault (600MiB) is documented, but block-builderwal.ingestion_time_range_slackdefault is now 2h in code whileconfiguration/_index.mdstill omits it underblock_builder.wal(shared WAL section still says 2m). - Docs update needed — #8062:
tempo-cli parquet rewritegained--row-group-size-bytes,--bloom-fp, and--bloom-shard-size-bytes(with inherit/default behavior). The command is not documented indocs/sources/tempo/operations/tempo_cli.md. - Docs update needed — #8058: Poller skips blocks with undecodable
meta.jsoninstead of failing the tenant poll, and emitstempodb_blocklist_corrupt_block_meta_total. Neither the behavior nor the metric appears indocs/sources/tempo/operations/monitor/polling.md.
