In sintesi

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.

Cos'è 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

❓ Domande frequenti

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.
