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

6 Worth-it Cloud Security Courses

-
Cloud security is critical to run cloud-applications. I have shared few courses useful for cloud security.

To get a job you need good training. Security courses are currently hot in the market.
  1. Cloud Security Hands-On Training: This course provides a solid foundation in cloud security, and includes a full day of hands-on labs to apply the principles in practice. We cover all the material needed to pass the Cloud Security Alliance Certificate of Cloud Security Knowledge (CCSK) exam, but add a pragmatic approach to immediate kick start your cloud security projects. For Black Hat we also add expanded material to show you how to take cloud security to the next level by leveraging DevOps techniques and the characteristics of the cloud.
  2. Cloud Security Fundamentals: An overview of security issues within each of these models will be covered with an in-depth discussion of the risks involved. This cloud security training course will go in-depth on architecture and infrastructure fundamentals for private, public and hybrid clouds, including a wide range of topics such as patch and configuration management, virtualization security, application security and change management. 
  3. Institute of information Security: In this course, we shall first discuss the characteristics of cloud computing and later on focus specifically on cloud security’s best practices taking reference from industry standards like NIST, OWASP, Cloud Security Alliance etc. We then look into the broad set of policies, technologies, and controls deployed to protect client data, applications and infrastructure associated with cloud computing.
  4. Cloud Security Training: In this course you will learn Virtualization Concepts and security, Risk Assessment on Cloud Migration and Emerging Threats
  5. Certification in Cloud Security:
  6. Cloud Security Essentials: In this course you will learn about Cyber-cloud and Mobile-security concepts.

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
