Path(s) to the data file(s) to open. Multiple files of the same format are concatenated into one table (not required with –generate-config, –clear-cache, or –remove-templates)
--skip-lines <SKIP_LINES>
Skip this many lines when reading a file
--skip-rows <SKIP_ROWS>
Skip this many rows when reading a file
--no-header <NO_HEADER>
Specify that the file has no header
--delimiter <DELIMITER>
Specify the delimiter to use when reading a delimited text file
--compression <COMPRESSION>
Specify the compression format explicitly (gzip, zstd, bzip2, xz) If not specified, compression is auto-detected from file extension
--debug
Enable debug mode to show operational information
--hive
Enable Hive-style partitioning for directory or glob paths; ignored for a single file
--parse-dates <BOOL>
Try to parse CSV string columns as dates (e.g. YYYY-MM-DD, ISO datetime). Default: true
--decompress-in-memory <DECOMPRESS_IN_MEMORY>
Decompress into memory. Default: decompress to temp file and use lazy scan
--temp-dir <DIR>
Directory for decompression temp files (default: system temp, e.g. TMPDIR)
--sheet <SHEET>

--clear-cache
Clear all cache data and exit
--template <TEMPLATE>
Apply a template by name when starting the application
--remove-templates
Remove all templates and exit
--sampling-threshold <N>
When set, datasets with this many or more rows are sampled for analysis (faster, less memory). Overrides config [performance] sampling_threshold. Use 0 to disable sampling (full dataset) for this run. When omitted, config or full-dataset mode is used
--pages-lookahead <PAGES_LOOKAHEAD>
Number of pages to buffer ahead of the visible area (default: 3) Larger values provide smoother scrolling but use more memory
--pages-lookback <PAGES_LOOKBACK>
Number of pages to buffer behind the visible area (default: 3) Larger values provide smoother scrolling but use more memory
--row-numbers
Display row numbers on the left side of the table
--row-start-index <ROW_START_INDEX>
Starting index for row numbers (default: 1)
--column-colors <BOOL>
Colorize main table cells by column type (default: true). Set to false to disable
