Data Ingestion components
a. You need to research and identify the different types of data (from structured to unstructured) and data ingest (e.g., batch, micro-batch, real-time), and briefly explain them.
(a) Data ingestion
Data ingestion is a processing of importing data for recent uses or storage devices in a database. It can fetch data from storage devices to real-time and batch processes. Data ingestion is a method through which data is transferred from one location to another location or sources where it will be saved and examined. Data may have come from different sources and different formats like CSV, RDBMS, S3 buckets, etc.
Data can invest in batch in real-time, and it is called lambda architecture. Data is imported at frequently planned periods while you ingest data in the group. When using batch processing to give extensive opinions of group data this strategy tries to balance the advantages of batch and real-time methods, while also using actual-time processing to give opinions of time-sensitive info/data.
Structured and unstructured data
Structured and unstructured data are totally different from each-others. Structured is easy way to search information by algorithms. Unstructured data are more likely human language which does not fit in relational database.
