Accelerate value from data: Migrating from batch to stream processing (ANT324)

Here's a detailed summary of the video transcription in markdown format, broken down into sections:

Evolution of Data Processing

• Humans and businesses have been collecting data for thousands of years, starting with clay tablets in ancient Mesopotamia.
• Data production and processing has exploded in the 21st century due to the ubiquity of the internet, smartphones, and e-commerce.
• Data is now being produced continuously, from diverse sources, and is being analyzed by many applications within businesses.

Modern Business Needs

• Businesses still require reporting, but also need the ability to generate faster insights and power AI/ML capabilities.
• Faster insights lead to better and faster decision-making, while AI/ML capabilities can provide differentiation for businesses.

Batch vs. Streaming Processing

• Batch processing is useful for powering business reporting and BI tools, but is insufficient for generating faster insights and powering AI/ML.
• Streaming processing can provide real-time data processing, enabling faster insights and better support for AI/ML use cases.

Streaming Architecture

1. Producing and Storing Data:

   • Use CDC (Change Data Capture) tools like AWS DMS or Debezium to stream data changes from databases to streaming storage like Amazon Kinesis or Apache Kafka.
   • This reduces load on databases and provides low-latency data ingestion.

2. Processing Data in Motion:

   • Use a managed service for Apache Flink to continuously process the streaming data, perform filtering, enrichment, and aggregation.
   • Flink's stateful processing capabilities enable complex event processing and machine learning inference.

3. Writing Data to Data Store:

   • Use a serverless service like Amazon Data Fusion to ingest data into different destinations, including data lakes like Apache Iceberg.
   • Iceberg supports updates and schema evolution, which are important for streaming use cases.

Key Takeaways

1. Streaming can enable real-time insights and synchronize systems with continuous data production.
2. Streaming can satisfy both latency-tolerant and latency-sensitive use cases, replacing the need for separate batch and streaming architectures.
3. Streaming technologies are becoming more mature, cost-effective, and easier to use, making them suitable for mission-critical workloads.
