类名称：Decimal
方法名：builder

Decimal.builder介绍

[英]Returns a SchemaBuilder for a Decimal with the given scale factor. By returning a SchemaBuilder you can override additional schema settings such as required/optional, default value, and documentation.
[中]返回具有给定比例因子的十进制的SchemaBuilder。通过返回SchemaBuilder，您可以覆盖其他模式设置，如必需/可选、默认值和文档。

/**
 * Returns a {@link SchemaBuilder} for a decimal number depending on {@link JdbcValueConverters.DecimalMode}. You

 * and documentation.
 *
 * @param mode the mode in which the number should be encoded
 * @param precision the precision of the decimal
 * @param scale scale of the decimal
 * @return the schema builder
