🚀 Final Thoughts

• 🔹 If you’re streaming real-time data, use Kafka + Flink + Druid/Superset.
• 🔹 If you need batch analytics, use Spark + Hadoop + Trino.
• 🔹 If you want a modern cloud solution, use BigQuery + Airbyte + Superset.
• 🔹 If you’re running ML on big data, use Spark ML + MLflow.

Here is the detailed architecture diagram of the Big Data Pipeline. It visually represents the data flow across ingestion, storage, processing, querying, visualization, monitoring, machine learning, and orchestration stages.

📌 How to Read the Diagram

1. Data Sources: Incoming data from Web Logs, Databases, IoT Sensors, API Feeds.
2. Data Ingestion: Kafka (real-time), NiFi, Airbyte, and Debezium (ETL and CDC tools) collect the data.
3. Data Storage: HDFS, S3, Cassandra, BigQuery, and Snowflake store raw data.
4. Data Processing:
   • Spark processes batch data.
   • Flink processes real-time data streams.
   • Trino enables SQL-based querying on structured data.
5. Data Querying & Analysis: Presto, Hive, and Druid allow complex queries.
6. Data Visualization: Superset & Grafana for dashboarding and insights.
7. Monitoring & Logging: Prometheus tracks system metrics, Elasticsearch logs real-time events.
