Frequently Asked Questions
How does TableView open Parquet files without a backend server?
TableView compiles DuckDB and Apache Arrow directly into WebAssembly (Wasm). When you drop a .parquet file, your browser executes the C++ query engine natively inside your tab.
Can I inspect compression codecs and metadata?
Yes! TableView displays the complete Parquet metadata header, including row group distribution, dictionary pages, and compression codecs (Snappy, ZSTD, GZIP, LZ4).
