This blog will discuss the frequently asked interview questions that might help you gain knowledge about Redshift and prepare you for the next interview.

RedShift Interview Questions

Q1: What is Redshift in AWS?

Amazon Web Service(AWS) Redshift is a fully managed big data warehouse service in the cloud that is rapid and potent enough to process and manage data in the range of exabytes. Redshift is built to handle large-scale data sets and database migrations by the company ParAccel (later acquired by Actian). It uses massive parallel processing (MPP) technology and provides a cost-effective and efficient data solution. The famous usage of Redshift is acquiring the latest insight for business and customers.

The major benefits provided by AWS Redshift include:

In-built security with end-to-end encryption.

Multiple query support that provides significant query speed upgrades.

It provides an easy-to-use platform that is similar to MySQL and provides the usage of PostgreSQL, ODBC, and JDBC.

It offers Automated backup and fast scaling with fewer complications.

It is a cost-effective warehousing technique.

Q3: Why use an AWS Data Pipeline to load CSV into Redshift? And How?

AWS Data Pipeline facilitates the extraction and loading of CSV(Comma Separated Values) files. Using AWS Data Pipelines for CSV loading eliminates the stress of putting together a complex ETL system. It offers template activities to perform DML(data manipulation) tasks efficiently.

To load the CSV file, we must copy the CSV data from the host source and paste that into Redshift via RedshiftCopyActivity.

Q4: How to list tables in Amazon Redshift?

The ‘Show table’ keyword lists the tables in Amazon Redshift. It displays the table schema along with table and column constraints. Syntax:

SHOW TABLE [schema.]table_name

Q5: How are Amazon RDS, DynamoDB, and Redshift different?

Below are the major differences:

Database Engine

The available Amazon RDS engines include Oracle, MySQL, SQL Server, PostgreSQL, etc., while the DynamoDB engine is NoSQL, and Amazon Redshift supports the Redshift(adapted PostgreSQL) as a database engine.

Data Storage

RDS facilitates 6 terabytes per instance, Redshift supports 16 terabytes per instance, and DynamoDB provides unlimited storage.

Major Usage

RDS is used for traditional databases, while Redshift is famous for data warehousing DynamoDB is the database for dynamically modified data.

Multi-Availability Zone Replication

RDS acts as an additional service while Multi-AZ replication for Redshift is Manual and for DynamoDB is Built-in.

Q6: How far Redshift is better in performance as compared to other data warehouse technologies?

Amazon Redshift is the easiest and fastest cloud data warehouse which facilitates 3 times better price-performance than other data warehouses. Redshift offers fast query performance at a comparatively modest cost to firms where datasets ranging in size from gigabytes to exabytes.

Q7: How do we load data into Redshift?

Several methods are available to load data into Redshift, but the commonly used 3 methods are:

The Copy command is used to load data into AWS Redshift.

Use AWS services to load data into Redshift.

Use the Insert command to load data into Redshift.

Q8: What is Redshift Spectrum? What data formats does Redshift Spectrum support?

Redshift Spectrum is released by AWS(Amazon Web Services) as a companion to Amazon Redshift. It uses Amazon Simple Storage Service (Amazon S3) to run SQL queries against the data available in a data lake. Redshift Spectrum facilitates the query processing against gigabytes to exabytes of unstructured data in Amazon S3, and no ETL or loading is required in this process. Redshift Spectrum is used to produce and optimize a query plan. Redshift Spectrum supports various structured and semi-structured data formats, including AVRO, TEXTFILE, RCFILE, PARQUET, SEQUENCE FILE, RegexSerDe, JSON, Geok, Ion, and ORC. Amazon suggests using columnar data formats like Apache PARQUET to improve performance and reduce cost.

Q9: How will the price of Amazon Redshift vary?

The Amazon Redshift pricing depends upon the type of node chosen by the customer to build his cluster. It mainly offers two types of nodes that differ in terms of storage and computation:

Dense Compute Nodes

These optimized computing nodes offer RAM up to 244GB and SSDs up to 2.5 terabytes. The lowest spec price for dc2.larges varies from 0.25$ to 0.37$ per hour, and the highest spec price for dc2.8x varies from 4.8$ to 7$ per hour.

Dense Storage Nodes

These nodes provide high storage capacity in two versions- a basic version(ds2.xlarge) with up to 2 TB HDDs and a higher version(ds2.8xlarge) with up to 16 TB HDDs. The cost of the basic version varies from 0.85$ to1.4$ per hour, and for the higher version is 6$ to 11$.

Q10: What are the limitations of Amazon Redshift?

It cannot be used as a live app database due to the slow processing speed of web apps.

There is no way to enforce uniqueness in AWS Redshift on inserted data.

It supports the parallel loading only for Amazon EMR, relational DynamoDB, and Amazon S3.


In this blog, we have seen some of the important interview questions that can be asked in AWS Redshift interviews. We had discussed a basic combination of theoretical and practical questions, but that’s not it. This blog will give you a basic understanding of what type of questions you expect. However, it’s recommended apart from these Redshift interview questions; you also practice the SQL commands to develop more understanding of data processing and transformations. The key takeaways from the above AWS Redshift questions are:

We learned about what is Redshift in AWS and how it is beneficial for the user.

We have seen how can we load CSV in Redshift using the data pipeline.

We understand how Redshift differs from RDS and DynamoDB.

We got an understanding of how we can show tables.

We have also discussed the basics of Redshift Spectrum and the limitations of Redshift.

Source: GCP Docs

Q4. What is a load balancer in GCP?

A load balancer is a service that distributes incoming network traffic across multiple backend instances or services to ensure that the workload is evenly distributed and that the system remains highly available and responsive to user requests.

Following load balancers available in GCP,

HTTP(S) Load Balancer

Network Load Balancer

Internal Load Balancer

Q5. What is a snapshot in GCP?

A snapshot is a point-in-time copy of a persistent disk. Snapshots are used for data backup, disaster recovery, and migrating data between regions.

GCP: Advance-Level Interview Questions Q1. What is Google Cloud CDN?

Google Cloud CDN (Content Delivery Network) is a network of servers situated globally that provides the content to users according to their geographical location. It helps in delivering web content, video, and other data quickly and reliably, enhancing the user experience.

Source: GCP Docs

Q2. How can you use the GCP BigQuery API to run a SQL query and fetch the results?

To use the GCP BigQuery API to run a SQL query and fetch the results, you can follow these steps:

from import bigquery # Set up the BigQuery client object # Build the query configuration query = ''' SELECT * FROM `bigquery-public-data.samples.natality` LIMIT 100 ''' query_config = bigquery.QueryJobConfig() query_config.query = query # Create and submit the query job query_job = client.query(query, job_config=query_config) # Wait for the job to complete query_job.result() # Retrieve the results and process them results = query_job.result() for row in results: print(row)

First, we need to create a client object using bigquery.Client() constructor. At that point we’ll characterize the SQL query which we need to execute. At that point, we’ll yield the query to the BigQuery benefit utilizing the client object’s query() method. This returns a query_job question that speaks to the job that was made to run the query. Able to at that point call the result() method on the query_job protest to get the comes about of the query.

Q3. Explain the use of VPC Peering in GCP.

VPC peering is a great networking tool that lets you link two virtual private clouds (VPCs) so they can chat with each other using private IP addresses. This can be super useful if you’ve got stuff spread out across different regions or want to keep certain resources isolated but still accessible.

By setting up a VPC peering connection between them, you can create a secure and private connection that doesn’t require any internet access. This way, your VPCs can share resources like databases, storage, or application services without exposing them to the public internet. Pretty nifty, huh?

Source: GCP Docs

Some use cases and benefits of VPC Peering in GCP:

Shared Resources

Cost Savings
