Infer-schema for CSV Files or automatic CSV schema detection feature in Snowflake is an important utility for data teams. Snowflake, has added support for schema detection that can now scan CSV & JSON files and "Infer Schema" table function can extract the column names and date type and help a data developer to create table automatically without any manual effort.
Traditionally, before loading data, permanent or transient tables are created with DDL SQL Statements and this can be an effort intensive task for large data projects can take any where between 5-15% of overall development effort (in man hours). This feature automatically reads a CSV file from a named stage location(s) and intelligently infers column names and data types This automation not only saves valuable time and effort but also reduces the risk of schema mismatches, ensuring data integrity throughout the data pipeline.
