2. The term "Big Data" refers to large
and complex datasets that cannot be easily managed,
processed, or analyzed using traditional data processing tools Big Data poses challenges such
as  volume (the sheer amount of data), velocity (the speed
at which data is generated and processed), variety (the different types of data sources), and  veracity (the reliability and accuracy of the data) Definition of Big Data Challenges of Big Data

3. Log Aggregation: It can be used
to aggregate log data from
multiple sources for centralized
monitoring and analysis Messaging System
for Microservices: Kafka acts as
a highly scalable
and fault-tolerant messaging
system for communication
between microservices in
a distributed architecture Real-time Data Pipeline: Kafka
is used for collecting, processing,
and delivering real-time data
streams from various sources
such as sensors, applications,
and databases Apache Kafka: Apache Kafka is
an open-source distributed streaming
platform designed for building real-time
data pipelines and streaming applications

4. Topics: Logical
channels
for organizing
and partitioning data
streams Consumers:
Applications that
subscribe to and
process data from
Kafka topics Producers:
Applications that
publish data to Kafka
topics Brokers: Kafka servers
responsible
for storing
and managing data
partitions Replication and Fault
Tolerance: Kafka
ensures data
durability and fault
tolerance through
data replication
across multiple
brokers 13. Architecture:

5. Kafka follows a publish-subscribe messaging model where producers
publish messages to topics, and consumers subscribe to topics to receive messages
in real-time LinkedIn utilizes Kafka for real-time activity tracking, monitoring, and data
integration across various services and systems How it Works Case Study

6. Apache Spark is a fast
and general-purpose cluster computing system
designed for large-scale data processing and analytics Large-scale Data Processing : Spark is used
for processing massive datasets in distributed
environments, enabling tasks like ETL (Extract,
Transform, Load) and batch processing Real-time Stream Processing : Spark Streaming allows for the processing of real-time data streams with
low latency, making it suitable for applications like
real-time analytics and monitoring Machine Learning and Graph Processing: Spark
provides libraries for machine learning ( MLlib )
and graph processing ( GraphX ), enabling advanced
analytics and algorithmic computations Use Cases: Definition and Purpose: Apache Spark:
