# Title: [FILE] Support custom separator in CSV adapter
## Description
This PR adds support for custom field delimiters (separators) in the CSV
adapter. previously, the adapter hardcoded the comma (`,`) as the separator,
preventing the use of other common delimiters like pipes (`|`) or tabs (`\t`).
## Changes
- Modified [CsvTableFactory] to parse an optional `separator` property from
the operand map.
- Updated [CsvTable], [CsvTranslatableTable], and [CsvEnumerator] to
propagate the separator character down to the reader.
- Updated `CsvStreamReader` to accept a custom separator in its constructor.
- Defaults to comma (`,`) if no separator is specified, preserving backward
compatibility.
## Example Configuration
Users can now specify a `separator` in their model JSON:
```json
{
"version": "1.0",
"defaultSchema": "TEST",
"schemas": [
{
"name": "TEST",
"type": "custom",
"factory": "org.apache.calcite.adapter.file.CsvTableFactory",
"operand": {
"file": "data.csv",
"separator": "|"
}
}
]
}
