My Talk at GCPUG-Taiwan on 2015/5/8.
You use BigQuery with SQL, but the internal work of BigQuery is very different from traditional Relational Database systems you may familiar with.
One of the way to understand how BigQuery works is to see it from the cost you pay for BigQuery. Knowing how to save money while using BigQuery is to know how BigQuery works to some extent.
In this session, let’s talk about practical knowledge (saving money) and exciting technology (how BigQuery works)!
Google BigQuery is Google's fully managed big data analytics service that allows users to analyze very large datasets. It offers a fast and easy to use service with no infrastructure to manage. Developers can stream up to 100,000 rows of data per second for near real-time analysis. BigQuery bills users per project on a pay-as-you-go model, with the first 1TB of data processed each month free of charge.
In this lecture we analyze document oriented databases. In particular we consider why there are the first approach to nosql and what are the main features. Then, we analyze as example MongoDB. We consider the data model, CRUD operations, write concerns, scaling (replication and sharding).
Finally we presents other document oriented database and when to use or not document oriented databases.
Google BigQuery is a cloud data warehouse and spreadsheet database that allows users to import, store, and query data in various formats like CSV, JSON, and Google Sheets. It provides a sandbox account with 10GB of free storage and 1TB of free queries per month. To use it, users create a BigQuery project, import data into datasets and tables, and then query the data using SQL syntax.

MS SQL Server is a database server produced by Microsoft that enables users to write and execute SQL queries and statements. It consists of several features like Query Analyzer, Profiler, and Service Manager. Multiple instances of SQL Server can be installed on a machine, with each instance having its own set of users, databases, and other objects. SQL Server uses data files, filegroups, and transaction logs to store database objects and record transactions. The data dictionary contains metadata about database schemas and is stored differently in Oracle and SQL Server.

Embarking on building a modern data warehouse in the cloud can be an overwhelming experience due to the sheer number of products that can be used, especially when the use cases for many products overlap others. In this talk I will cover the use cases of many of the Microsoft products that you can use when building a modern data warehouse, broken down into four areas: ingest, store, prep, and model & serve. It’s a complicated story that I will try to simplify, giving blunt opinions of when to use what products and the pros/cons of each.
The document summarizes BuzzNumbers' transition from using SQL Server to MongoDB as their database. It discusses problems they faced with SQL Server like scalability issues and performance problems with large datasets. It then covers why they chose to use MongoDB, including its ability to scale horizontally and handle large volumes of writes and reads. Finally, it discusses lessons learned in moving to a NoSQL database and using MongoDB and .NET to build their analytics product.
This document summarizes new and updated Azure data and analytics services. It highlights the general availability of SQL Server 2017 on Windows and Linux, Azure Database Migration Service, Azure Databricks, new performance tiers for Azure SQL Data Warehouse and HDInsight Kafka. It also mentions new capabilities for Azure Machine Learning, Azure Data Factory, Azure Database for MySQL and PostgreSQL, and preview releases of Azure SQL Database Managed Instance and other services.
This document provides an overview of relational databases and the emergence of alternative database technologies like NoSQL. It discusses the dominance and stability of relational databases but also some of their limitations for certain use cases. It introduces NoSQL databases and why they emerged, focusing on their scalability and flexibility compared to relational databases. The document describes different types of NoSQL databases and how they handle concepts like schemas, transactions and scaling. It provides examples of when different database types may be more suitable and discusses additional concepts like aggregates, consistency models and sharding.
This document summarizes new features in SQL Server 2008 for developers. It covers new data types like spatial, XML, and CLR types as well as features like table valued parameters, change tracking, and ADO.NET Entity Framework support. It also discusses enhancements to Integration Services, reporting services, and the core SQL Server engine.
Open Source für den geschäftskritischen EinsatzMariaDB plc
The document summarizes MariaDB's 2017 roadshow. It discusses that MariaDB is building an easy to use, extendable database that can be deployed on premise, in the cloud, or in a hybrid environment. It also notes that MariaDB provides enterprise features like high availability, performance, and security while being fully open source and encouraging community collaboration. Finally, it provides information on where MariaDB is used and how organizations can get support from MariaDB.
The document discusses data service level agreements (SLAs) in public cloud environments. It explains that achieving availability, consistency, and scalability is challenging due to Brewer's CAP theorem. It reviews strategies for relational and NoSQL databases to handle these tradeoffs, including dropping consistency or availability depending on needs. Code examples demonstrate typical operations for Cassandra, MongoDB, and Neo4J NoSQL databases. The conclusion recommends choosing solutions based on requirements and migrating to NoSQL as needed to address scaling issues.
The document discusses scalable storage systems and key-value stores as an alternative to traditional databases. It provides an overview of vertical and horizontal scalability. Traditional databases are not well-suited for scalable systems due to their complexity, wasted features, and multi-step query processing. Key-value stores offer simpler data models and interfaces that are designed from the start for scaling across hundreds of machines. Performance comparisons show key-value stores significantly outperforming traditional databases. The document also outlines how key-value storage systems work at the aggregation and storage layers.

evolution of Dremel(2006)
Initially launched in 2010
WebService on top of Dremel Technology
More of a hybridsystem (columnar + nested data)

12. Data Types
Redshift:Closer to the StandardSQLdatatypes (e.g. INT4,
INT8) but doesnotsupport the full range of PostgreSQL
data types
BigQuery: Smaller set of data types supported. But...
13. Data Types
Redshift:Very basic support for JSON
BigQuery: Support for Array and STRUCT types. Nesteddata
structures are first class citizens.
15. Data Manipulation
BigQuery used to be appendonly, now it supportsUpdates
andDeletes (DML). But still limited.
Redshift always had this Supported via SQL but with a
catch (Vacuum)
16. Table Manipulation
BigQuery: Limited and expensive via standard SQL, or via
HTTP API (but you have to unload and reload the table).
Redshift: Supported via SQL
Both support views but not materialized
18. Data Consistency
Redshift supports transactions VS BigQuery No
Deduplication harder to be achieved on BigQuery (costly
also).
Even more complex when we go streaming.
21. Cluster Management
Here is where BigQueryreallyshines. It is fullymanaged with
supportforHA.
Redshift doesnotabstract completely the hardware from the
user and it is difficult to implement it as a HA service.
This changes with Spectrum.
26. Amazon Redshift Google BigQuery
Resources capped by your cluster size
No quotas related to inserts/updates
etc
2,000 slots per account
Encourages the append only model with
strict DML quotas
Both have a limit of 50 concurrent Queries
Cluster resizing a pain with Redshift.
39. Amazon Redshift Google BigQuery
More predictable costs
More intuitive data modeling (Analysts)
Options for optimizations
Easier & cheaper to start with
Good for nested data
Easier to work with time series
