com.clickhouse.client.api.data_formats.RowBinaryFormatWriter

All Implemented Interfaces:

ClickHouseBinaryFormatWriter

public class RowBinaryFormatWriter
extends Object
implements ClickHouseBinaryFormatWriter

This class is intended to help writing data in row binary format. It handles Nullable and Defaults. It implements record and commit approach row-by-row. It means that data is not written immediately but it is stored until commitRow() is called.
