Google BigQuery

Features

BigQuery was born from Dremel, which is Google's distributed query engine. Dremel can handle gigabytes of data in seconds. This includes running sophisticated queries on several servers in parallel to speed up processing.

Tree Architecture

Dremel and BigQuery can grow to thousands of computers by organising calculations as an execution tree. Incoming requests are routed via mixers, which modify them before distributing them to leaf nodes known as slots by a root server. The dirty job of reading and filtering input is done in parallel by the leaf nodes. The findings are sent back down the tree to the mixers, who blend them and send them to the root as the query's response.

Serverless Service

In most data warehouse setups, organisations must select and commit to the server hardware on which calculations will run. Administrators must consider performance, security, flexibility, and dependability. The use of a serverless paradigm overcomes this issue.

In a serverless method, the processing is automatically distributed among many devices working in parallel. When using BigQuery's serverless method, data engineers and database administrators may focus less on infrastructure and more on offering servers and creating insights from data.

SQL and Programming Language Support

BigQuery can be accessed using standard SQL, which is something that many people are already acquainted with. BigQuery also comes with client libraries for Java, Python, C#, Go, Node.js, PHP, and Ruby, which may be used to build data-accessing applications.

Security

When data in BigQuery is at rest or in transit, it is automatically encrypted. BigQuery also offers the capability of isolating jobs and managing multitenant security. Organisations may take a comprehensive perspective of data security since BigQuery is intimately linked with the security features of other GCP products.

Google Cloud Identity and Access Management allow users to share datasets (IAM). Individuals and groups can have access to datasets, tables, and views based on permissions specified by administrators.

The policy controls in Google's Virtual Private Cloud prevent anyone outside of our business from accessing data or attempting to export data to unauthorised third parties. IAM and VPC work together to close security gaps across Google Cloud Platform products.

Pricing

BigQuery price is determined by the amount of data stored and queries processed. There are two tiers of storage charges. Data that has been updated within the last 90 days are charged per month for active storage. Data that hasn't been modified in the last 90 days are charged at a lower monthly rate.

In addition, there are two price structures for enquiries. The amount of data handled by each query determines the on-demand cost. Customers pay a one-time fee for dedicated querying resources rather than per-query fees with flat-rate pricing. This pricing is intended for businesses that prefer a set price.

Using Google BigQuery

BigQuery is a Google Cloud Platform service. Customers of Google Cloud Platform can use their familiar web interface console to access the service. Google BigQuery APIs can also be accessed by current GCP SDKs and CLI tools, in addition to the UI Console.

Getting started with Google Cloud BigQuery is a straightforward procedure. Any dataset in a standard format, such as CSV, Parquet, ORC, Avro, or JSON, may be used immediately. If you don't have any data in mind for Google BigQuery, you can study and use datasets from Google Cloud Public Datasets.
