Batch vs real-time ingestion in Hadoop - Quick Revision & Key Differences

Recall & Review

beginner

What is batch ingestion in data processing?

Batch ingestion means collecting data over a period and then processing it all at once. It's like gathering all your mail for a week and reading it on Sunday.

beginner

What does real-time ingestion mean?

Real-time ingestion means processing data immediately as it arrives. Imagine getting a text message and reading it right away.

beginner

Name one advantage of batch ingestion.

Batch ingestion can handle large amounts of data efficiently and is simpler to manage because it processes data in groups.

beginner

Why might real-time ingestion be preferred in some cases?

Real-time ingestion is preferred when quick decisions are needed, like fraud detection or live monitoring, because it processes data instantly.

intermediate

Give an example of a Hadoop tool used for batch ingestion.

Apache Hadoop MapReduce is commonly used for batch ingestion to process large data sets in batches.

Which ingestion type processes data immediately as it arrives?

A Real-time ingestion

B Batch ingestion

C Delayed ingestion

D Scheduled ingestion

Real-time ingestion processes data instantly as it arrives.

Which Hadoop tool is mainly used for batch processing?

A Apache Flink

B Apache Hadoop MapReduce

C Apache Kafka

D Apache Storm

Apache Hadoop MapReduce is designed for batch processing large data sets.

What is a key benefit of batch ingestion?

A Processes data instantly

B Requires complex setup

C Only works with small data

D Handles large data efficiently

Batch ingestion efficiently handles large volumes of data by processing in groups.

Real-time ingestion is best suited for:

A Live monitoring and alerts

B Historical data analysis

C Data archiving

D Monthly reports

Real-time ingestion supports live monitoring and instant alerts.

Which statement is true about batch ingestion?

A It processes data one record at a time

B It requires real-time streaming tools

C It processes data in groups after collection

D It cannot handle large data volumes

Batch ingestion collects data and processes it in groups after a period.

Explain the difference between batch and real-time ingestion with examples.

Think about how often data is processed and the tools used.

Describe scenarios where batch ingestion is better than real-time ingestion and vice versa.

Consider speed needs and data volume.
