How to Extract Profile Data Correctly from Linkedin

Image
                                                                           meta ai Almost all companies today rely on LinkedIn to extract candidate profiles during hiring or onboarding. However, despite widespread use, even large enterprises frequently fail to extract complete and accurate profile data. The result is broken or partial imports, dozens of mismatches and formatting errors, and missing sections like certifications, experience, or education. This often forces candidates to manually re-enter or correct the information—costing them time, creating frustration, and negatively impacting their experience. To read LinkedIn profile details (including licenses and certifications ) after authorization, follow this short and structured approach: ✅ Prerequisites LinkedIn Developer Account A reg...

Databrickls Lakehouse & Well Architect Notion

Image
Let's quickly learn about Databricks, Lakehouse architecture and their integration with cloud service providers : What is Databricks? Databricks is a cloud-based data engineering platform that provides a unified analytics platform for data engineering, data science and data analytics. It's built on top of Apache Spark and supports various data sources, processing engines and data science frameworks. What is Lakehouse Architecture? Lakehouse architecture is a modern data architecture that combines the benefits of data lakes and data warehouses. It provides a centralized repository for storing and managing data in its raw, unprocessed form, while also supporting ACID transactions, schema enforcement and data governance. Key components of Lakehouse architecture: Data Lake: Stores raw, unprocessed data. Data Warehouse: Supports processed and curated data for analytics. Metadata Management: Tracks data lineage, schema and permissions. Data Governance: Ensures data quality, security ...

Masking Data Before Ingest

Masking data before ingesting it into Azure Data Lake Storage (ADLS) Gen2 or any cloud-based data lake involves transforming sensitive data elements into a protected format to prevent unauthorized access. Here's a high-level approach to achieving this: 1. Identify Sensitive Data:    - Determine which fields or data elements need to be masked, such as personally identifiable information (PII), financial data, or health records. 2. Choose a Masking Strategy:    - Static Data Masking (SDM): Mask data at rest before ingestion.    - Dynamic Data Masking (DDM): Mask data in real-time as it is being accessed. 3. Implement Masking Techniques:    - Substitution: Replace sensitive data with fictitious but realistic data.    - Shuffling: Randomly reorder data within a column.    - Encryption: Encrypt sensitive data and decrypt it when needed.    - Nulling Out: Replace sensitive data with null values.    - Tokenization:...

Some Questions and Topics for Data Engineers and Data Architects

  How to do an incremental load in ADF? Incremental loading in Azure Data Factory (ADF) involves loading only the data that has changed since the last load. This can be achieved by using a combination of source system change tracking mechanisms (like timestamps or change data capture) and lookup activities in ADF pipelines to identify new or updated data. What is data profiling? Data profiling is the process of analyzing and understanding the structure, content, quality, and relationships within a dataset. It involves examining statistics, patterns, and anomalies to gain insights into the data and ensure its suitability for specific use cases like reporting, analytics, or machine learning. Difference between ETL and ELT? ETL (Extract, Transform, Load) involves extracting data from source systems, transforming it into a suitable format, and then loading it into a target system. ELT (Extract, Load, Transform) involves loading raw data into a target system first, then transforming it ...

Stream Processing Window Functions

Image
  Photo by João Jesus: pexel A common goal of stream processing is to aggregate events into temporal intervals, or windows. For example, to count the number of social media posts per minute or to calculate the average rainfall per hour. Azure Stream Analytics includes native support for five kinds of temporal windowing functions. These functions enable you to define temporal intervals into which data is aggregated in a query. The supported windowing functions are Tumbling, Hopping, Sliding, Session, and Snapshot. No, these windowing functions are not exclusive to Azure Stream Analytics. They are commonly used concepts in stream processing and are available in various stream processing frameworks and platforms beyond Azure, such as Apache Flink, Apache Kafka Streams, and Apache Spark Streaming. The syntax and implementation might vary slightly between different platforms, but the underlying concepts remain the same. Five different types of Window functions Tumbling Window (Azure St...

Azure Data Factory Transform and Enrich Activity with Databricks and Pyspark

In #azuredatafactory at #transform and #enrich part can be done automatically or manually written by #pyspark two examples below one data source #csv another is #sqlserver with #incrementalloading Below is a simple end-to-end PySpark code example for a transform and enrich process in Azure Databricks. This example assumes you have a dataset stored in Azure Blob Storage, and you're using Azure Databricks for processing. ```python # Import necessary libraries from pyspark.sql import SparkSession from pyspark.sql.functions import col, lit, concat # Initialize SparkSession spark = SparkSession.builder \     .appName("Transform and Enrich Process") \     .getOrCreate() # Read data from Azure Blob Storage df = spark.read.csv("wasbs://<container_name>@<storage_account>.blob.core.windows.net/<file_path>", header=True) # Perform transformations transformed_df = df.withColumn("new_column", col("old_column") * 2) # Enrich data enriched...
