A major part of any data pipeline is the cleaning of data. Depending on the project, cleaning data could mean a lot of things. But in most cases, it means normalizing data and bringing data into a format that is accepted within the project. Read more... “Cleaning and Normalizing Data Using AWS Glue DataBrew”

Getting started with Chalice to create AWS Lambdas in Python – Step by Step Tutorial

If you’re into serverless stuff, you already know what is AWS Lambda. But if you don’t know, AWS Lambda is a serverless service provided by Amazon where you can create ‘functions’ and deploy them in AWS, which you can run without having any server instances (such as EC2).

Invoke an AWS Lambda Function from another Lambda Function

I recently discovered that you can't invoke more than one Lambda function in AWS for an S3 event, with the same prefix and suffix (or just with the same suffix, which was the issue in my case). So I wanted a way to invoke one Lambda function from another Lambda function. If you're feeling kind of lost, check out the problem statement in my Github project. That could possibly add some context to the problem. If you don't want to go there, I'll try to explain it here again. The Problem and the Requirement In one of our projects, we have a Lambda function which is invoked whenever a text file is uploaded to a particular S3 bucket. The Lambda function takes

How to automatically trigger AWS Lambda functions using CloudWatch

If you have AWS Lambda functions which need to be triggered periodically, like CRON jobs, there are many ways to achieve this. But I recently discovered a very easy and AWS-way of doing this, which makes life a lot easier. So, there are a lot of ways you can trigger Lambda functions periodically. One of the most common ways I've see people doing this is adding an API Gateway to the Lambda function, and then calling that API periodically as a CRON job from one of the machines in the setup. I actually thought this is how you're supposed do to that. Okay, let me make this clear. I'm not a DevOps guy. I just learn these things as and when

Integrate AWS DynamoDB with Spring Boot

Here is another POC to add to the growing list of POCs on my Github profile. Today, we’ll see how to integrate AWS DynamoDB with a Spring Boot application. This is going to be super simple, thanks to the AWS Java SDK and the Spring Data DynamoDB package. Let’s get started then. Dependencies First, as usual, we need to create a Spring Boot project, the dependencies of which look like: <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>com.amazonaws</groupId> <artifactId>aws-java-sdk-dynamodb</artifactId> <version>1.11.573</version>

Getting Started With Apache Airflow


Apache Airflow is another awesome tool that I discovered just recently. Just a couple of months after discovering it, I can’t imagine not using it now. It’s reliable, configurable, and dynamic. Because it’s all driven by code, you can version control it too. Read more... “Getting Started With Apache Airflow”

Soon after the lockdown, when we all started working from home, there was a sudden increase in the number of people who wanted to write machine learning code. And not just any machine learning code, but one specifically to check if a person is wearing a mask or not.

Explore your Amazon S3 data online using Filestash


Amazon’s S3, or Simple Storage Service, has become one of the most used cloud services today. We use it for all kind of purposes, including but not limited to data lakes, intermediary storage, persistence layer for databases, etc. I know people who use S3 as their personal online storage, as an alternative for services such Google Drive and Dropbox.
