Expand description

Line-delimited JSON read options

Fields

schema: Option<SchemaRef>

The data source schema.

schema_infer_max_records: usize

Max number of rows to read from JSON files for schema inference if needed. Defaults to DEFAULT_SCHEMA_INFER_MAX_RECORD.

file_extension: &'a str

File extension; only files with this extension are selected for data input. Defaults to “.json”.
