3. Data Transformation

Once data extraction is accomplished, transformation is vital. Data transformation ensures accuracy, consistency, and compatibility with target systems. Tasks for data transformation also include data normalization and cleansing.

4. Data Storage

Data analysts must store transformed and validated data in target systems like data warehouses, data lakes, or operational warehouses. 

Now, let’s examine some of the common types of data ingestion that serve distinct purposes within data pipelines. 

5 Types of Data Ingestion

Data ingestion is the first step in building a scalable data pipeline to ensure that raw data is collected, processed, and transformed for analysis. The overall choice of ingestion types depends on data volume, processing speed, and organizational requirements. 

Here are the common types of data ingestion:

1. Batch Processing

• Batch processing involves data accumulation that occurs over a specific time before data processing. 
• Batch processing is straightforward, dependable, and minimizes the impact on overall system performance. 
• It is not an ideal type for real-time processes. 

2. Real-time Processing

• The process provides instant valuable insights for efficient decision-making processes, enabling on-spot analysis. 
• The method is optimal for applications like fraud detection that depend on immediate decision-making processes.

3. Stream Processing

• Stream processing provides similar functionality to real-time processing, and ingested data is continuously analyzed. 
• The process demands high computing power and bandwidth. 

4. Microbatching

• Data ingestion occurs in small batches, providing real-time insights without resource constraints. 
• It strikes the optimal balance between real-time and batch p[processing for data pipelines. 

5. Lambda Architecture 

• The process includes functionality and benefits of both real-time and batch processes.  
• It handles real-time data streams and simultaneously processes large sets of historical data, providing a cohesive solution for data ingestion. 

Batch processing is dependable. However, real-time ingestion is key to instant actions. 

Techniques for Data Ingestion 

Data ingestion techniques provide diverse solutions to address various needs and technical expertise. 

Here are some of the prevalent techniques for data ingestion depending on specific business requirements:

1. Extract, transform, load (ETL)

• ETl is a well-established technique for batch processing. 
• It initiates with data extraction followed by data transformation and loading data into various target destinations. 
• The systematic process of ETL ensures data consistency and removes duplicate data for comprehensive data analysis. 

2. Data Virtualization

• The technique involves creating a virtual layer that allows data integration from multiple sources.
