8 Ways to Optimize AWS Glue Jobs in a Nutshell

-
Image
  Improving the performance of AWS Glue jobs involves several strategies that target different aspects of the ETL (Extract, Transform, Load) process. Here are some key practices. 1. Optimize Job Scripts Partitioning : Ensure your data is properly partitioned. Partitioning divides your data into manageable chunks, allowing parallel processing and reducing the amount of data scanned. Filtering : Apply pushdown predicates to filter data early in the ETL process, reducing the amount of data processed downstream. Compression : Use compressed file formats (e.g., Parquet, ORC) for your data sources and sinks. These formats not only reduce storage costs but also improve I/O performance. Optimize Transformations : Minimize the number of transformations and actions in your script. Combine transformations where possible and use DataFrame APIs which are optimized for performance. 2. Use Appropriate Data Formats Parquet and ORC : These columnar formats are efficient for storage and querying, signif

Differences: AWS Vs Other Cloud models

-
The first key difference between AWS and other IT models is flexibility. Using traditional models to deliver IT solutions often requires large investments in new architectures, programming languages, and operating systems.
comparison of cloud services

Why AWS is Superior

Although these investments are valuable, the time that it takes to adapt to new technologies can also slow down your business and prevent you from quickly responding to changing markets and opportunities.

When the opportunity to innovate arises, you want to be able to move quickly and not always have to support legacy infrastructure and applications or deal with protracted procurement processes.

Flexibility

In contrast, the flexibility of AWS allows you to keep the programming models, languages, and operating systems that you are already using or choose others that are better suited for their project.

Easy to Learn

You don’t have to learn new skills. Flexibility means that migrating legacy applications to the cloud is easy and cost-effective. Instead of re-writing applications, you can easily move them to the AWS cloud and tap into advanced computing capabilities.

Support

Building applications on AWS are very much like building applications using existing hardware resources. Since AWS provides a flexible, virtual IT infrastructure, you can use the services together as a platform or separately for specific needs. AWS run almost anything—from full web applications to batch processing to offsite data back-ups.

Integration

In addition, you can move existing SOA-based solutions to the cloud by migrating discrete components of legacy applications. 

Typically, these components benefit from high availability and scalability, or they are self-contained applications with few internal dependencies. Larger organizations typically run in a hybrid mode where pieces of the application run in their data center and other portions run in the cloud.

Summary

Once these organizations gain experience with the cloud, they begin transitioning more of their projects to the cloud, and they begin to appreciate many of the benefits outlined in this document. Ultimately, many organizations see the unique advantages of the cloud and AWS and make it a permanent part of their IT mix

Here's a quick resolution for import datetime Python error . The reason is your .py python script name and datetime  are the same. I'll show you how this error happens and its resolution.   Here's the Resolution for ImportError I've created a script called 'datetime.py.' to check whether the minute value is 'odd' or not. During the import of my python script, I got the import error cannot import name datetime. My Script: datetime.py My script's intention is to find whether the minute value is odd or not. Python Logic from datetime import datetime odds = [ 1 , 3 , 5 , 7 , 9 , 11 , 13 , 15 , 17 , 19 , 21 , 23 , 25 , 27 , 29 , 31 , 33 , 35 , 37 , 39 , 41 , 43 , 45 , 47 , 49 , 51 , 53 , 55 , 57 , 59 ] right_this_minute = datetime.today().minute if right_this_minute in odds: print ( "This minute seems a little odd." ) else : print ( "Not an odd minute." ) ImportError I have imported my datetime.py from Linux. It gives an error

How to Check Kafka Available Brokers

Here's the command to check the list of brokers present in a Kafka Cluster. You can say the Broker is the heart of the Kafka cluster. In simple terms, it works as a process. The main function is to receive messages from publishers and gives permission to access messages by consumers. How to Check Available Brokers in Kafka Here is the command: linux$  ./zookeeper-shell.sh zookeeper-IPaddress:2181 | "ls /brokers/ids" Just use the above command to get the number of brokers present in your host (Kafka Cluster). What is Default Broker-id in Kafka  The default broker id is -1 . When you create a new broker, it adds to -1. Then, it gives a new broker id. The broker ids will be generated from  reserved.broker.max.id + 1. Types of broker ids. Use assigned Zookeeper generated broker id. According to Wiki: Kafka runs on a cluster of one or more servers (called brokers), and the partitions of all topics are distributed across the cluster nodes.  Additionally, partitions are replicat

SQL Query: 3 Methods for Calculating Cumulative SUM

-

SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than or
