Overview of BigQuery

BigQuery by Google is yet another popular cloud-based service that is also termed as a big data analytics web service that intends to process large datasets that are specified as read-only. The design of this service by Google intends to analyze data in row order, with the use of SQL syntax. The entire service runs over the Google Cloud Storage infrastructure, which has the compatibility of being accessed through the REST-oriented API.

BigQuery was primarily released in 2011 and was introduced in the face of an externalized version of the Dremel query service software. Both BigQuery and Dremel employ columnar type storage to implement fast data scanning and impose a tree-type architecture to enhance the results and dispatch the queries across the computer clusters.

When BigQuery was leveraged as the Dremel form, it was used within Google for tracking the data that reciprocates device installation. Apart from that, it also helped in creating crash reports and processing spam analysis. Since the time BigQuery came into the scene, its features were improved, and then in 2013, the timestamps and data joins were brought into the scene. Moving on, Google also added data insert potential to the BigQuery service aspects.

It is a serverless, scalable, and cost-efficient cloud warehouse, especially for data, that is designed for making your business agile. It helps businesses get a 360-degree view of their data and their implementation. The enterprises can decide upon which data they want to process, store and analyze, irrespective of whether they are internal or external to an organization, with BigQuery. Moreover, it allows you to be aware of the situations associated with the data and be responsive to all of the events that are taking place within the organization in real-time. With the high availability of your organizational data, you can make the necessary insights available for the business users to make decisions driven by data.

BigQuery intends to help you secure your data and add governance to its use and implementation. It is evident that you need to secure your data and make it accessible for the enabled stakeholders inside or outside your enterprise. With BigQuery, your enterprise will speed itself in terms of accessing and utilizing the data without the necessity of waiting for a periodic gap.

BigQuery Pricing

BigQuery helps you eradicate the necessity of provisioning the individual VMS or instances for use with BigQuery. BigQuery allocates all of the computing resources, depending upon your need and necessity. Along with that, you also get the potential to reserve the computing capacity in the form of specific slots. Hence, it represents virtual CPUs! The pricing structure is specified by Google for enabling the service for your enterprise.

The pricing schemes are specified into two important components, such as analysis pricing and storage pricing. Analysis pricing intends to put up the cost for processing queries, adding up SQL queries, scripts, user-defined functions, and DML and DDL statements. Storage pricing intends to put up the cost for storing data that you will be loading onto BigQuery.

BigQuery also puts up charges for several other operations or services that include streaming inserts and the use of the BigQuery Storage API. You can check the information upon data ingestion and data extraction pricing to get a clear glimpse of the cost-bearing factors. Apart from that, there are two pricing models specified for enabling BigQuery services, which include on-demand pricing and flat-rate pricing.

On-Demand Pricing Model

Within this model, you are intended to pay a charge for the count of bytes that are processed by each of the queries. BigQuery is offering a free service for 1st 1TB of query data that gets processed every month. Whether the data is stored over a Drive, Cloud Bigtable, or Cloud storage, or in BigQuery, the on-demand pricing is based upon the usage aspects. Queries on-demand will cost you $5.00 per TB, after the first free 1TB every month exceeds!

BigQuery makes use of a columnar data structure that intends to charge you upon the data processed within those columns. The total data for every column is calculated upon the data types within the column. You can prefer to calculate your data size by using this dedicated calculator. Remember that you are not charged for the queries that will return in the form of an error. The charges are often rounded off based upon the nearest MB.

Flat-Rate Pricing Model

In case you are looking for high-volume service adaptation with monthly charges, then it is better to go for flat-rate pricing. Refer to this official link for enabling a flat-rate pricing model for your usage of BigQuery. Right after you enroll in the flat-rate pricing, you need to purchase the processing capacity of the query, which is then measured within the BigQuery slots. The queries intend to consume this processing capacity, and there is no billing aspect imposed upon these processed bytes.

If the demand of your capacity exceeds the commitment capacity upon the flat-rate pricing model, then BigQuery will be queuing up the slots to ensure that you are not charged any additional amount for the same. You can buy a minimum of 100 slots over flat-rate pricing, and the increment in the future can be done with the next 100 slots. You will be charged around a $2000/month flat rate for every 100 slots that you buy over the model. If you pay a fixed annual amount, then the monthly expense will drop down to $1700 per month.

The Architecture of Google BigQuery Data Warehouse 

BigQuery is primarily based upon Dremel technology, which is a tool that has been implemented within Google for ten years now. But apart from that, there are colossus and Jupiter Network architectures involved within the service as well. Here is a brief elaboration upon Dremel, Colossus, and Jupiter Network.

Dremel- This architecture apportions all of the slots to the queries, as per the needs of the enterprise data. It intends to maintain the balance among all the users who intend to query at a single instance. You need to keep in mind that you can get thousands. One user can intend to get over thousands of slots for running their select queries within this architecture. And, Dremel intends to make your queries run faster. All of the BigQuery requests are fueled by the power of Dremel query engine architecture.

Jupiter Network- Jupiter Network is the internal data center that helps BigQuery in the pursuit of separating compute and storage from one another.

Colossus- BigQuery is heavily relying upon Colossus, which is defined as the latest generation distributed file system by Google. Each of the data centers listed under Google operates upon its own Colossus cluster. Each of the Colossus clusters consists of sufficient disks to give out thousands of specific disks to a single BigQuery user at one time. Apart from that, Colossus has the potential to handle replication, distribution management, and disk crash recovery aspects.

Productive Perks of Utilizing BigQuery
