Part 2: Latency in Data Integration, Batch vs Real-Time, with 7 Practice Questions

Part 2 of the DAMA-CDMP series. This lesson covers latency in Data Integration and Interoperability (DMBOK2, section 1.3.2). Every term is labeled by what it is: a latency level, a style, a method, a data form, or a tool. We follow one question: how soon must the target see the change? What you will learn: Latency levels: batch, event-driven, real-time synchronous, streaming Styles: synchronous vs asynchronous Data forms: snapshot and delta Methods: micro-batch, change data capture (data-based and log-based), two-phase commit, enterprise service bus Real tools: Debezium, Oracle GoldenGate, SQL Server CDC, Kafka, RabbitMQ, Amazon SQS, MuleSoft, Redis, SAP HANA 7 practice questions with explained answers Chapters 0:00 Introduction 0:23 What is latency 0:49 The big picture 1:36 Latency levels 2:08 Batch 2:40 Snapshot and delta 3:20 Micro-batch 3:56 Batch timing risks 4:24 Change data capture 4:58 Data-based CDC 5:37 Log-based CDC 6:15 Event-driven and ESB 6:50 Event-driven example 7:13 Load order 7:50 Asynchronous 8:20 Asynchronous examples 8:44 Real-time synchronous 9:12 Two-phase commit 9:42 Synchronous trade-offs 10:13 Streaming and low latency 10:44 How low latency works 11:24 Putting it together 12:04 Summary 12:32 Practice questions 12:42 Question 1 13:33 Question 2 14:12 Question 3 14:53 Question 4 15:27 Question 5 16:04 Question 6 16:48 Question 7 Disclaimer: This is an independent educational summary.
