Why is schema on the fly considered significant in data analytics?

Schema on the fly is significant in data analytics primarily because of the flexibility it offers. This approach allows for dynamic data processing where the schema can adjust in real time based on the incoming data's structure. This means that analysts and users can work with various data formats without needing to define a schema beforehand.

In traditional data analytics, a rigid schema is often necessary, requiring significant planning and pre-definition. However, with schema on the fly, data can be ingested and processed regardless of its structure, supporting various use cases such as machine data, unstructured data, and rapidly changing data environments. This flexibility enables businesses to react quickly to new data sources and insights, enhancing their ability to make data-driven decisions efficiently.

The other aspects, such as increased data redundancy, complex processing, and manual processing requirements, are typically seen as drawbacks in data analytics. They do not align with the advantages of schema on the fly, which is all about adapting to diverse data without cumbersome preprocessing.
