BigQuery vs. Redshift: Comparison

Features BigQuery Redshift
User-defined functions Using SQL and JavaScript Using SQL SELECT clause or Python
Encryption Supports by default Can be enabled
Table Partitioning Supports partition to improve query performance Redshift doesn't support table partitioning, whereas Amazon Redshift Spectrum does.
Streaming Data BigQuery supports streaming data directly. Separate AWS applications, such as Amazon Kinesis can be used for streaming data.

Redshift and BigQuery are highly efficient and robust data warehousing solutions with a significant user base. However, determining which is better ultimately depends on your business requirements. To make an informed decision, let's see a detailed comparison of Redshift vs. BigQuery. 

BigQuery vs. Redshift: Integrations

Both Redshift and BigQuery offer a range of options to connect and integrate with other tools and services.

Redshift can be integrated well with other AWS products and services, such as S3 for data storage, AWS Glue for data cataloging, and AWS Lambda for serverless event-driven data processing. It also supports JDBC and ODBC connections, enabling integration with various business intelligence (BI) tools and data integration solutions.

BigQuery, as part of the Google Cloud Platform (GCP) ecosystem, integrates seamlessly with other GCP services, including Google Cloud Storage for data import and export, Cloud Dataflow for data processing, and Cloud Dataproc for big data analytics. You can effortlessly integrate BigQuery with popular BI tools like Tableau, Looker, and Data Studio, for data visualization and analysis.

BigQuery vs. Redshift: Performance Optimization

Both BigQuery and Redshift provide performance optimization features to optimize query execution. However, they use different techniques and strategies to achieve these. 

BigQuery eliminates the need for manual indexing, as its internal architecture and indexing techniques are highly optimized. BigQuery's query planner employs a cost-based optimization approach. It evaluates various factors, such as data size, distribution, and available resources, to determine the optimal query execution plan. This enables BigQuery to perform efficiently by minimizing resource usage and execution time.

Redshift requires manual indexing and tuning to optimize query performance. You can create and manage indexes on specific columns to speed up query execution for frequently queried fields. Redshift's performance can be enhanced by defining sort and distribution keys on tables. Sort keys determine the order of data storage, while distribution keys determine how data is distributed across nodes, reducing data movement during query execution.

BigQuery vs. Redshift: Usability

Amazon Redshift and Google BigQuery present distinct approaches tailored to varying preferences and requirements.

BigQuery offers a user-friendly web-based console with intuitive features like query history and autocomplete, making it easier to manage and query data. It is well-integrated within the Google Cloud ecosystem, providing seamless interoperability with other Google Cloud services. BigQuery also benefits from extensive documentation and a supportive community, resulting in a relatively smooth learning curve.

Conversely, Redshift might rely on third-party tools for query development and management, which may require additional setup and configuration. While it supports SQL as the querying language, the development experience may be less user-friendly than BigQuery. However, Redshift is part of the AWS ecosystem and integrates well with other Amazon services. While the learning curve for Redshift may be slightly steeper, it provides comprehensive documentation and resources to navigate the platform effectively.

BigQuery vs. Redshift: Pricing Models

Both BigQuery and Redshift offer flexible pricing models that cater to different needs.

BigQuery provides both on-demand and flat-rate options. With on-demand pricing, you pay for the storage used and the data processed by your queries. Conversely, flat-rate pricing offers predictable costs with a fixed monthly fee based on your query capacity. This is ideal for people with consistent workloads or those who prefer predictable billing.

Redshift pricing depends on the number and type of compute nodes used. You can choose between on-demand pricing and reserved instance pricing. On-demand pricing is billed based on the number of hours you use your cluster and the type of nodes you use. However, with Amazon Redshift Serverless, you have the flexibility to start using the service at a low cost of $3 per hour. You only pay for the compute capacity that the data warehouse consumes. 

BigQuery vs. Redshift: Encryption

Data encryption acts as an additional layer of protection for sensitive data. It ensures that encrypted data remains unreadable in the event of data exposure. However, the default settings for encryption differ between Amazon Redshift and BigQuery.

In Amazon Redshift, encryption for data at rest and in transit is not enabled by default. To encrypt data at rest, you must explicitly enable it either during the initial cluster setup or by modifying an existing cluster to utilize AWS Key Management Service encryption. Similarly, encryption for data in transit should also be explicitly enabled.

On the contrary, BigQuery takes a proactive approach to encryption. By default, it automatically encrypts all data, both at rest and in transit, without manual intervention. Furthermore, it allows you to tailor encryption settings to suit your needs and compliance requirements.
