𝐖𝐡𝐚𝐭 𝐢𝐬 𝐚 𝐒𝐭𝐚𝐠𝐞 𝐢𝐧 𝐒𝐧𝐨𝐰𝐟𝐥𝐚𝐤𝐞 ? A stage specifies where data files are stored (i.e. “staged”) so that the data in the files can be loaded into a table. Stage is a location of files, that can be internal or external to snowflake Stage Types 1.   External Stages 2.   Internal Stages 1.   User Internal Stage 2.   Table Internal Stage 3.   Named Internal Stage We will discuss about external stage 𝐄𝐱𝐭𝐞𝐫𝐧𝐚𝐥 𝐒𝐭𝐚𝐠𝐞𝐬 An external stage is the external cloud storage location where data files are stored. Loading data from any of the following cloud storage services is supported regardless of the cloud platform that hosts your Snowflake account: Amazon S3 Google Cloud Storage Microsoft Azure   •       An external stage is a database object created in a schema. •       This object stores the URL to files in cloud storage. •       Also stores the settings used to access the cloud storage account (Storage Integration Object). •       Create stages using the CREATE STAGE command.    example:        CREATE STAGE my_s3_stage  URL='s3://mybucket/path/'  STORAGE_INTEGRATION = my_s3_integration  CREDENTIALS=(AWS_KEY_ID='your_aws_key_id' AWS_SECRET_KEY='your_aws_secret_key')  FILE_FORMAT = (TYPE = 'CSV' FIELD_OPTIONALLY_ENCLOSED_BY = '"' COMPRESSION = 'GZIP'); #dataengineer #dataengineering #python #snowflake #datawarehouse #cloud #aws

Hello Folks!!! Today, I will be sharing how you could use the PySpark to read data from a Json File on MultiLine parameters. And to read a file in json and csv or avro data format type, you can use the below Pyspark code: df = spark.read.csv("URL or Directory"), if you want to define the schema and header then use: df = spark.read.csv|json|avro("URL",header=True, Inferschema=True). Then when you execute the query, you can now use the df.show() to display the out of the Query. Do you know that a Select statement could be used as well to read data from a single Column, multiple Columns etc: df.select("Column1", "Column2").show() - execute the query on the DataBricks and it would output just the two selected Columns. I will share below a screenshot of the dataframe used to read data in the JSON format as a MultiLine. I am a lover of data and enjoy using services in Amazon Web Services (AWS), Microsoft Azure (Azure) and Google Cloud Platform (GCP) to perform data transformation and analytics. #DataEngineer #DataBaseAdministrator #DataAnalyst #D365FOEngineer

Did you know? 🤔 You can like 👍 this post while learning something new! 🚀 Learning AWS through Projects – Day 5 📅 Nested JSON Data File Analysis using AWS Glue DataBrew & QuickSight 🛠️ Project: Analyze and visualize nested JSON data using AWS services. Steps: 1️⃣ Upload nested JSON data to an S3 bucket’s input folder. 2️⃣ Create an AWS Glue DataBrew project and import the nested data. 3️⃣ Unnest the JSON using DataBrew recipes, making the data easier to work with. 4️⃣ Export the cleaned and transformed data to the S3 bucket’s output folder. 5️⃣ Visualize the final dataset using Amazon QuickSight for insights and reporting. Key Services: S3, AWS Glue DataBrew, Amazon QuickSight 📊 Breakdown of the Process: Data Ingestion via S3 🗂️: The nested JSON file is uploaded to the input folder in an S3 bucket. This is where the raw data is stored before processing. Data Transformation with AWS Glue DataBrew 🔄: A DataBrew project is created to handle the data transformation. Using the recipe feature, we unnest the JSON, making it easier to analyze by flattening complex structures. Export Clean Data to S3 🚀: After transformation, the clean data is exported back to an S3 output folder, ready for visualization. Visualization with QuickSight 🔍: The cleaned dataset is imported into Amazon QuickSight, where it’s visualized using charts and dashboards to gain insights. This process simplifies complex data using AWS Glue DataBrew and makes it ready for analysis using QuickSight. Perfect for turning complex nested data into actionable insights! 🚀 Amazon Web Services (AWS) #AWS #DataEngineering #DataBrew #S3 #QuickSight #DataTransformation #JSONAnalysis

🔍 TIL: The Curious Case of the "Invisible" BigQuery Dataset 👻 Today I encountered an interesting scenario in #GoogleCloud that taught me a valuable lesson about service accounts and permissions. 🤓 The Scenario: ⚡ I had a BigQuery dataset that I could clearly see, but when trying to delete it through the UI or CLI, GCP kept telling me it didn't exist. Frustrating, right? 😅 The Plot Twist: 🎯 Turns out, the dataset was created using a service account, and here's where it gets interesting - without proper IAM permissions, BigQuery treats the dataset as non-existent from your user account's perspective! 🔐 Key Learnings: 💡 1. Just because you can see a resource doesn't mean you have full access to it 👀 2. Service accounts "own" the resources they create 🔑 3. The "dataset doesn't exist" error can sometimes mean "you don't have permissions" ⚠️ The Solution: ✨ I wrote a Python script using the service account credentials, and voila - the dataset was successfully deleted! 🎉 Pro Tips for Cloud Engineers: 🚀 • Always document which service accounts own which resources 📝 • Grant necessary IAM permissions to user accounts during resource creation 🔒 • Consider implementing automated permission management in your IaC ⚙️ #CloudComputing ☁️ #GoogleCloudPlatform #BigQuery #TechLessons #CloudEngineering #DataEngineering #IAM #CloudSecurity

🚀 Exciting Update! 🎉 I’m thrilled to share that I've completed a key module in Data Engineering: Big Data on AWS Cloud - Athena & EC2. Here's a quick dive into my learning journey: 🔍 Working with Athena & S3: Leveraged AWS Athena to query data stored in S3 buckets, creating tables with metadata stored in AWS Glue Catalog. This allowed me to execute SQL queries directly on data in S3. 📊 💡 Optimizing Data Queries: Initially, querying CSV files in S3 with Athena resulted in scanning entire files. To optimize, I used Databricks to convert the CSV files to Parquet format, which is columnar and more efficient for querying. This significantly reduced the data scanned by Athena queries, improving performance. 🚀 🔧 Apache Spark Integration: Explored Athena’s new support for Apache Spark, a serverless service that allows complex data processing using PySpark within Athena workgroups. This added flexibility for handling intricate data tasks using Spark's robust engine. 🔄 🛠️ Glue Crawler: Utilized AWS Glue Crawler to automatically infer the schema of data stored in S3, streamlining the process of creating accurate data tables. 🧩 🤖 Serverless Advantage: Athena’s serverless nature means no cluster management; charges are based on data scanned (SQL Trino engine) or compute resources used (Apache Spark engine). Ideal for scheduled tasks where efficiency and cost-effectiveness are key. ⏰ 💻 Hands-on with EC2: Gained practical experience in creating and managing EC2 instances through both the AWS Management Console and AWS CLI, enhancing my cloud infrastructure skills. 🌐 This module has been a fantastic blend of theory and practical application, and I’m excited to leverage these skills in real-world scenarios! 🌍 🙏 A big shoutout to Sumit Mittal for creating such an insightful course. #DataEngineering #BigData #AWS #Athena #EC2 #Serverless #Databricks #S3 #Glue #Parquet #SQL #Trino #Spark #LearningJourney #TechSkills
