Today I was working with a small MySQL data set. The data provided by a CSV file and needed to load it into AWS RDS MySQL. Since the RDS does not support the Load data inline. So I have manually convert the CSV file to .sql file. But the problem statement is, in CSV the date time column had two digit year format and while converting into sql it considered the day part as year and automatically added 20 in the beginning. MySQL has makedate function , but it didn’t work for me. My entire data for the year 2018.
Redshift will help to handle a massive data warehouse workload. I used to manage some redshift cluster in past. Whenever the developers or I wanted to test something on RedShift, we generally take a snapshot and then launch a new cluster or launch it from the automated snapshot. This is fine for Ad-Hoc workloads. Think something like, if your developers want to continually test and run their sample queries on the cluster on daily basis with updated data then there will be a headache for AWS Admins, So I have prepared a shell script for this to mate this process and it’ll send the email alerts when any one of the steps are failed. This script will help you to automate
In my previous blog post I have explained how to automatically create AWS Athena Partitions for cloudtrail logs between two dates. That script will help us to create the partitions till today. But cloudtrail will generate log on everyday. So I was thinking to automate this process too. For this automation I have used Lambda which is a serverless one. This will automate AWS Athena create partition on daily basis. Your Lambda function needs Read permisson on the cloudtrail logs bucket, write access on the query results bucket and execution permission for Athena.
A WS Athena is a schema on read platform. Now Athena is one of best services in AWS to build a Data Lake solutions and do analytics on flat files which are stored in the S3. In the backend its actually using presto clusters. So most of the Presto functions are support and you can use native SQL query to query your data. You can create partitions to speedup your query and reduce the cost for scanning. Here Im gonna explain automatically create AWS Athena partitions for cloudtrail between two dates. When it is introduced I used this for analyze CloudTrail Logs which was very helpful to get some particular activities like who launched this instance, track a particular user’s activity and etc.

Windows Servers are in AWS will show some glitches in sometimes. My previous article explains how Windows Server 2016 had some issues with DNS Suffix and Forwarders. This time I got a chance to play around with PowerShell automations. The requirement is automatically add EC2 instances to Active directory domain during the instance launch. It might be an On Demand purpose ec2 or launched by an Auto scaling group.
