📝 WalkthroughWalkthroughThe ANS beneficiary crawler now uses categorical dtypes and explicit DataFrame cleanup. Its flow compares source updates against coverage, uploads Parquet files explicitly, and sets job memory to ChangesANS beneficiary pipeline
Estimated code review effort: 3 (Moderate) | ~20 minutes Mergeability Score: 🔵 Low · up to The PR changes ANS update detection to use actual table coverage, but a remaining metadata write path still records the materialization timestamp instead of the covered date, which can cause future updates to be missed. The change is mergeable with explicit owner awareness or follow-up to eliminate that stale write path. Possibly related issues

Prevent stale RawDataSource.Update.latest from blocking the flow.
register_source_coverage_task() only advances the source update if file_last_date is newer. If the stored source value is after the current month, May/June 2026 coverage records can become stale while sync_table_coverage_task() continues to update only Table.Update. Add an explicit repair for the stale source coverag or a supported force-overwrite path for this poll/commit loop.

A migração pro poll.py que este PR propunha não é mais necessária: o #1783 já corrigiu poll_source_for_update via compare_against, e br_ans_beneficiario já usa esse default corrigido. Mantido só o que continua valendo independente do mecanismo de poll: - RAW_COLLUNS_TYPE: colunas de texto categóricas (baixa/média cardinalidade) trocadas de str para category — reduz bastante o footprint do DataFrame sem mudar o valor persistido no parquet. - MODALIDADE_OPERADORA recasteada para category depois do remove_accents; del df + gc.collect() por estado em parquet_partition — sem isso a memória de cada estado se acumulava até o gc.collect() do loop de fora, já causou OOM num arquivo pequeno logo depois de um grande. - source_format="parquet" nos dois upload_to_gcs: crawler_ans grava .parquet, e sem declarar o formato o dump_header procurava .csv e não achava nada. - job_variables={"memory": "3Gi"}: pico medido em produção após a otimização foi ~1.78Gi; 3Gi dá ~1.7x de margem. - compare_against="coverage" explícito no poll (já era o comportamento via default desde o #1783; deixado explícito por consistência com os outros 26 flows). Também exclui models/world_aiddata_gcdf/code do Pyrefly (mesmo padrão do br_tse_eleicoes/us_harvard_cbdb/us_cfpb_hmda: pacote .py com imports relativos ao cwd, não notebook) — estava quebrando o type check na main, sem relação com esta mudança.

O #1783 moveu commit_source_update_task pra logo após o poll, removendo a chamada antiga do fim do flow em todos os arquivos afetados. O #1798, mergeado depois mas cortado de uma base anterior a esse merge, ainda tinha essa chamada antiga e só editou parâmetros dela (date_format). O merge do git combinou as duas sem detectar a duplicação lógica — commit_source_update_task passou a ser chamado duas vezes por run. Sem impacto de dados (é idempotente), só uma escrita redundante.

Contexto
Este PR originalmente propunha migrar
br_ans_beneficiariopara o modelo de poll novo (register_source_coverage_task/check_source_is_ahead_of_table_task/sync_table_coverage_task), o mesmo caminho que o #1760 propunha para obr_me_caged.Isso não é mais necessário: o #1783 (mergeado) já corrigiu a causa raiz —
poll_source_for_updatecomparando contraTable.Update.latestem vez da cobertura real — restaurando a escolha viacompare_against.br_ans_beneficiariojá usa esse default corrigido ("coverage") sem precisar de nenhuma migração de mecanismo. Ver #1781 e o #1760 (fechado pelo mesmo motivo) para o histórico completo.O que este PR faz agora
Só o que continua valendo independente do mecanismo de poll:
RAW_COLLUNS_TYPE: colunas de texto categóricas (baixa/média cardinalidade — UF, sexo, faixa etária, modalidade, município, plano) trocadas destrparacategory. Reduz bastante o footprint do DataFrame em memória sem mudar o valor persistido no parquet (Arrow grava a string real via dicionário; BigQuery/dbt leem como STRING normalmente).MODALIDADE_OPERADORArecasteada paracategorydepois doremove_accents(que devolvestrpuro);del df+gc.collect()por estado emparquet_partition— sem isso a memória de cada estado se acumulava até ogc.collect()do loop de fora emcrawler_ans, que só roda depois dos 27 arquivos.
