The ability to handle data tremendously has given AWS Redshift the power to provide valuable insights.

Moreover, it works at an incredible speed by creating a new cluster within a few minutes. That alone is the reason for companies to use Redshift!

What Is AWS Redshift Based On?

AWS Redshift is based on PADB, which is based on PostgreSQL. So, it’s safe to say that Redshift is based on PostgreSQL, but not entirely, as it has its own uniqueness.

However, if you are familiar with PostgreSQL, you will be able to learn the Redshift features quickly.

History of Amazon Redshift

Like the other AWS services, Amazon Redshift is also not that old. It was introduced in 2012 as the first cloud-based data warehouse for AWS users. However, it is not a native Amazon product.

ParAccel is the company that built Redshift, and Amazon spent $20 million to get it from them. They spent the money on the licensure of using the ParAccel Analytic Database (PADB) code.

PADB for Amazon Redshift

PADB was unique among its competitors for its columnar database. It used commodity hardware so using it for cloud-based data storage was ideal.

ParAccel made quite a fortune from the Amazon deal, but Redshift proved more valuable and profitable for Amazon!

What Does AWS Redshift Do?

Following are some of the features that determine the working of AWS Redshift:

  • AWS Redshift uses Online Transaction Processing (OLTP).
    • It allows the organization of data into columns and rows based on the nature of the workload.
    • Row-oriented systems are famous for their efficiency with small operations.
    • Column-oriented systems are popular for their speed in accessing large datasets.
  • It works on Massively Parallel Processing (MPP).
    • The divide and conquer strategy is applied to large datasets.
    • Massive processing task is broken down into smaller tasks.
    • The small jobs are distributed to different processors for simultaneous computations.
    • The divide-and-conquer method saves time.
  • It offers end-to-end encryption of data.
    • Redshift has customizable encryption options.
    • Users can configure encryption based on their needs.
    • They can use one of the two methods: customer-managed key or AWS-managed key.
    • They can choose between Hardware Security Module (HSM) or AWS Key Management Service.

What Is Amazon Redshift Service?

Amazon Redshift service uses a data warehousing solution to improve the processing of large datasets. The service works on MPP, so there are no delays due to the high volume of data.

Using MPP technology, the service offers speed by breaking large processing jobs into smaller tasks. It delivers output quickly and remains unmatched in cloud-based data storage.

Users have the power to encrypt any Redshift operation and protect their data from potential harm. There is also the familiarity factor with similar features as PostgreSQL, so the service can work well with SQL queries.

What Is AWS Redshift Spectrum?

Amazon Redshift has various features, and one of the most popular is Redshift Spectrum. Here are the characteristics of AWS Redshift Spectrum:

  • It offers complex, efficient, and fast analysis of cloud-stored objects.
  • The analysis is seamless given its embedded in the Amazon framework.
  • It can process data inside an S3 bucket.
  • As a result, it saves effort and time by analyzing the given data.

What Is AWS Redshift and How Is It Different from RDS?

AWS Redshift differs from RDS based on the following features:

AWS RedshiftRDS
Redshift works best with millions of rows of queries, thanks to the sophisticated query optimizer.RDS performs better with queries that do not test its limits. It’s perfect for queries that require low data scans.
Redshift requires administrative tasks to be conducted manually.RDS has a simple architecture, so it requires low maintenance. Most administrative tasks are automated.
Redshift requires the user to manage the unique constraints in insertion keys.RDS is rational data storage that thrives on row-oriented systems. It also supports unique key constraints.

What Is Amazon Redshift ODBC Driver?

ODBC is a powerful Amazon Redshift driver that helps you connect with Redshift data in real-time.

If you have an application that supports ODBC, you can directly access the data from that application. Following features make the ODBC driver so unique and crucial for Amazon Redshift:

  • Based on PostgreSQL and custom-made to connect with Amazon Redshift.
  • Enables real-time data access.
  • Provides SQL-92 capabilities for NoSQL data of Redshift.
  • Allows flexible querying and automatic schema generation.

What Is AWS Redshift Cluster?

Amazon Redshift data warehouse has computing resources. They are called nodes. When these nodes are organized in a group, we call it an AWS Redshift cluster. Each cluster is unique in Redshift and has one or more databases. It also runs the Redshift engine.

  • Each cluster has a Leader node and Compute nodes. The leader node is always only one, but Compute nodes can be more than one.
  • The Leader node has the task of getting in touch with client applications.
  • It receives queries and parses them to develop query execution plans.
  • It coordinates with the compute nodes for parallel execution of those queries.
  • It returns the aggregated results to the applications.

What Is AWS-Lambda-Redshift-Loader?

AWS Lambda Redshift Loader is the function of sending data from AWS Lambda to Redshift. Suppose you have the AWS Lambda Amazon Redshift Database Loader along with the Active Amazon Redshift Cluster. In that case, you can follow these steps to move data:

  • Download the AWS Lambda Amazon Redshift Database Loader.
  • Make configurations to the Redshift Cluster and allow access from external sources.
  • Enable the Lambda Function.
  • Configure an event source to take requests from the S3 buckets for Amazon Lambda.

What Is AWS Redshift and Glue?

AWS Glue and Amazon Redshift work in unison when needed to move data.

When data is taken into or out of an Amazon Redshift cluster, AWS Glue helps Redshift by issuing COPY and UNLOAD statements. This results in maximum throughput.

AWS Glue uses temporary credentials to work with the Redshift cluster, but the credentials expire within an hour, which becomes problematic when working on long-running tasks.

What Is Amazon Redshift Serverless?

Although Amazon Redshift is a real-time data warehousing service, it also comes with a serverless option.

Amazon Redshift Serverless makes analysis of data easier by eliminating the need to spend time on setting up a data warehouse and managing it.

The Redshift Serverless enables users to get helpful insight by uploading and querying data.

The performance of a Serverless data warehouse is fast and efficient, with the option to scale in seconds automatically. It also saves costs for users!

What Is Amazon Redshift vs S3?

AWS Redshift and Simple Storage Service (S3) are often confused as one service. Most newcomers are unaware of the distinct difference between these Amazon services, but you can understand it with this:

Amazon RedshiftAmazon S3
Redshift is a data warehouse service.S3 is an object storage service.
It deals with structured data that is ingested into the warehouse.It can work with any size or structure of data. There is no need for predefined details.
