Schema inference is the automatic derivation of a data’s structure and types from the actual data itself, typically used when no explicit schema is provided. During ingestion or auto-detection, the system looks at samples of the incoming data to determine field names, data types (such as integers, strings, booleans, dates), and nested structures. This lets you load diverse or evolving data quickly without needing to define a schema upfront, and it helps the pipeline understand how to parse and validate records as they come in.

Think of it as the data teaching the system its own shape: you gain speed and flexibility when you’re unsure of the exact format or you’re dealing with semi-structured sources like JSON or CSV with varying rows. Of course, inferred schemas aren’t perfect—types can be guessed and may require refinement later, especially after examining more data or enforcing strict validation. This approach is about discovering structure automatically, not about requiring an explicit schema, not limited to text data, and not about converting data to a specific storage format like Parquet.
