• Bug Fixes
  • Improved data processing reliability by handling input files individually.
  • Added clear validation when no input files are available.
  • Outputs now consistently follow the configured partitioning behavior, supporting either a consolidated result or separate file-based partitions.

📝 Walkthrough

Walkthrough

The CVM crawler now processes non-partitioned and partitioned outputs through separate paths, rejects empty file lists, and returns the output directory. CVM FI flow comments document staggered scheduling and monthly no-op polling.

Changes

CVM processing

Layer / File(s)	Summary
CVM file processing pipelines/crawler/cvm/tasks.py	_clean_standard_data raises ValueError for empty input, saves one non-partitioned output from the first file, or saves each file as a partition.
CVM FI flow schedule pipelines/datasets/br_cvm_fi/flows.py	Comments document the staggered schedule, BigQuery slot contention avoidance, monthly source cadence, and no-op polling.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to fe79c

The crawler behavior change is bounded, but the new scheduling comment incorrectly describes the daily Informe Diário source as monthly. Scope the cadence statement by table before merge to avoid misleading operators.

Scope the cadence statement.

The comment says that the source is monthly for all six flows. documentos_informe_diario is updated daily by the CVM. Scope this statement to the monthly tables, or document the cadence per flow. (dados.cvm.gov.br)
