Em resumo

BigQuery is Google Cloud's fully managed data warehouse for analytics at scale. Advanced skills include optimization (slots, clustering), advanced SQL (window functions, arrays, structs), real-time ingestion, machine learning integration, and cost control.

O que é BigQuery Advanced

BigQuery Advanced encompasses optimization, performance tuning, and advanced SQL patterns for Google Cloud's serverless data warehouse. It includes cost management (slots, clustering, partitioning), real-time ingestion (Streaming API, Change Data Capture), machine learning (BQML), and integration with ecosystem tools (Looker, Dataflow, Vertex AI). Advanced practitioners architect data solutions for petabyte-scale analytics. - Petabyte Scale: Handles analytics at unlimited scale without infrastructure management

❓ Perguntas frequentes

▶What is the difference between BigQuery standard and BigQuery Flex Slots?
Standard = monthly commitment (100 slots minimum). Flex = hourly billing (60 slots minimum). Flex for variable workloads.
▶How do I optimize BigQuery costs?
Partition tables by date, cluster by hot columns, use approximate functions, avoid SELECT *, enable result caching.
▶What is BigQuery BI Engine and when should I use it?
In-memory cache for fast queries on aggregated data. Worth it for dashboards with <100GB data, repeated queries.
▶Can I join large tables in BigQuery without exploding costs?
Yes; use broadcast joins (small table), avoid cross joins, leverage clustering to prune data before joins.
▶What is the BigQuery Storage API and why does it matter?
Allows columnar data export, Apache Arrow integration, faster exports than JSON. Essential for ML pipelines.
▶How do I use BigQuery ML for predictions?
CREATE OR REPLACE MODEL statement with training data; BQML auto-trains and deploys models without Python.
▶What is the typical latency for real-time ingestion into BigQuery?
Streaming API: ~35 seconds latency. Batch: sub-second after load job completion. Real-time dashboards need BI Engine.
