Batch Processing
•Batch processing processes huge data volumes within a specific time after production.
•Batch processing compiles a large volume of data all at once.
•Processing data size if finite and specified.
•Input graph in batch processing is static.
Stream Processing
•Stream processing processes continuous data in real-time as it is produced.
•In-stream processing is done in intervals as soon as data is produced.
•Stream processing data size is unknown and infinite.
•In-stream processing, the input graph is dynamic.

Batch Processing vs Stream Processing
Batch processing is done on a large data batch, and the latency can be in
minutes, days, or hours. It requires the most storage and processing resources
to process big data batches.
The latency of real-time data processing is in milliseconds and seconds, and it
processes the current data packet or several of them. It requires less storage for
processing recent or current data pocket sets and has fewer computational
requirements.
Streaming data analyzes continuous data streams, and the latency is guaranteed
in milliseconds. It requires current data packet processing; hence the processing
resources must be alert to meet guarantees of real-time processing.

Batch Processing vs Stream Processing
In Batch Processing it processes over all or most of the data but In
Stream Processing it processes over data on rolling window or most
recent record. So Batch Processing handles a large batch of data
while Stream processing handles Individual records or micro batches
of few records.
In the point of performance the latency of batch processing will be in
a minutes to hours while the latency of stream processing will be in
seconds or milliseconds.

What is Batch Processing?
Batch processing refers to the processing of blocks of data that have already been
stored over a period of time. For example, processing transactions that have been
performed by a financial firm in a week. This data contains millions of records for a
day that can be stored as a file or record. The particular file will undergo processing
at the end of the day for various analyses that the firm requires and it will be a time
taking process.
Batch processing is ideal for very large data sets and projects that involve
deeper data analysis. The method is not as desirable for projects that involve speed
or real-time results. Additionally, many legacy systems only support batch processing.

6.
Batch Processing Use cases?
Batch processing is used in a variety of scenarios, from simple data transformations
to a more complete ETL pipeline. In the context of big data, batch processing may
operate over very large data sets, where the computation takes a significant amount
of time. It works well in situations where you don’t need real-time analytics results or
when it is more important to process large volumes of data to get detailed insights
rather than to get fast analytics results.
•Real-time transfers and results are not crucial
•Large volumes of data need to be processed
•Data is accessed in batches as opposed to in streams
•Complex algorithms must have access to the entire batch

What is Stream Processing
Stream processing is a big data technology that allows us to process data in real-time
as they arrive and detect conditions within a small period of time from the point of
receiving the data. It allows us to feed data into analytics tools as soon as they get
generated and get instant analytics results.
Stream processing is ideal for projects that require speed and nimbleness. The
method is less relevant for projects with high data volumes or deep data analysis.
Stream processing is useful for tasks like fraud detection, social media sentiment
analysis, log monitoring, analyzing customer behavior, and more.

Batch Processing vs Stream Processing
•The batch processing model requires a set of data that is collected over time
while the stream processing model requires data to be fed into an analytics tool,
often in micro-batches, and in real-time.
•The batch Processing model handles a large batch of data while the Stream
processing model handles individual records or micro-batches of few records.
•In Batch Processing, it processes over all or most of the data but in Stream
Processing, it processes over data on a rolling window or most recent record.
•From a performance point of view, the latency of the batch processing model will
be in minutes to hours while the latency of the stream processing model will be in
seconds or milliseconds.
•Batch processing is a lengthy process and is meant for large quantities of
information that aren’t time-sensitive whereas Stream processing is fast and is
meant for information that is needed immediately.

Batch Processing vs Stream processing
Batch processing is the processing of transactions in
a group or batch. There is no user interaction
required once batch processing is running. This
differentiates batch processing from transaction
processing, which involves processing transactions one
by one and requires user intervention.

12.
Batch Processing vs Stream processing
Stream processing is the process of analyzing
streaming data in real-time. Analysts are able to
continuously monitor a stream of data to achieve
various goals.
Stream processing is a low-latency way to capture
information about events while they are in transit,
processing the data. A data stream, or event stream,
can include almost any type of information: social
network or web browsing path data, factory production
and other process data, stock or financial transaction
details, patient data in a hospital, machine learning
system data, IoT (Internet of Things).
