Format Details
FWF
FWF (Fixed-Width Format) is a plain-text data format where each column occupies a predetermined number of character positions in every row, with no delimiter characters between fields. It originated on mainframes and is still common in government data releases, financial industry feeds, and legacy enterprise system exports. FWF files require a separate schema or data dictionary to correctly parse the column boundaries, making them less self-describing than CSV.
Parquet
Apache Parquet is an open-source binary columnar storage format designed for efficient analytical data processing across the big data ecosystem. Its columnar layout enables excellent compression ratios and fast query execution when only a subset of columns is needed. Parquet is the de facto standard format for data lakes and is natively supported by Apache Spark, Hadoop, Presto, Snowflake, and most modern data processing platforms.
