  - getPicosecondTimestampMapping
```
public abstract TimestampPrecision getPicosecondTimestampMapping()
```
    Controls how BigQuery TIMESTAMP(12) (picosecond precision) columns are mapped to Beam schema types.
    Standard TIMESTAMP(6) columns are mapped to FieldType.DATETIME, which only support up to millisecond precision. This option allows mapping TIMESTAMP(12) columns to logical types Timestamp.MILLIS, Timestamp.MICROS, Timestamp.NANOS or preserve full picosecond precision as a STRING type.
    This option has no effect on TIMESTAMP(6) (microsecond) columns.
    Defaults to TimestampPrecision.NANOS.
