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

OpenStack Private Cloud, What IT Developers Should Learn

An example of OpenStack Usage: The second largest car manufacturer in the world, Volkswagen Group, will use the open-source cloud computing platform OpenStack to build a private cloud that will host websites for its brands VW, Audi, and Porsche, and will be a platform for innovating automotive technology, the company announced Wednesday.

For the past two years, VW officials at the company’s Wolfsburg, Germany, headquarters debated what platform to use. VW decided to first build out a private cloud based on OpenStack that will eventually span thousands of physical nodes across multiple data centers in the U.S., Europe, and Asia. Eventually, VW hopes to incorporate public cloud resources to create a hybrid cloud, said officials with VW’s consultant, Mirantis.

When fully built out, VW’s private cloud could be one of the top five or 10 largest OpenStack-based clouds in production, said Mirantis co-founder and chief marketing officer Boris Renski. According to the OpenStack Foundation’s user survey in October 2015, only 7% of OpenStack production deployments surpassed 1,000 nodes. Only 2% of OpenStack deployments were in the industrial/manufacturing industry.
“The Group IT Cloud is a new way to deliver Volkswagen applications at any scale, in a single global network, consistent across VW brands,” wrote Mario Mueller, Corporate Director IT Operational Services & Infrastructure Technologies, Volkswagen Group in an email interview. “Over time, all net new applications will run on this cloud which will naturally replace most of the legacy systems.” It will not replace legacy systems but instead will host most of the company’s newly developed applications.

What is All About OpenStack

It’s built entirely atop x86 hardware, using a Red Hat operating system and the Kernel Virtual Machine (KVM) hypervisor (95% of OpenStack production clouds use KVM, OpenStack’s user survey shows) with Mirantis’ licensed OpenStack distribution provisioning the virtual machines.

VW officials said they’re using OpenStack’s Neutron/OVS/VXLan technology for networking and Ceph for storage, with others likely to be added. Renski said VW is in the final stages of choosing a platform as a service (PaaS) layer to act as an application development and hosting environment that would run on top of the OpenStack IaaS.

Here's a quick resolution for import datetime Python error . The reason is your .py python script name and datetime  are the same.

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
