- `lines`: How many input lines may be part of a JSON value. The default, `multiple`, allows individual JSON values to span multiple lines. Specify `single` to limit support to newline-delimited JSON (NDJSON), a subset of JSON which does not allow a new-line inside a value.

## Output configuration

- `buffer_size_records`: Maximum number of records to batch into a single output Parquet file (output connectors only). When this threshold is reached, the encoder flushes the buffer to the transport. The default is `100000`.

## Example

In this example, we configure a table to load data from a Parquet file.
