HostColumnVector.ColumnBuilder	HostColumnVector.ColumnBuilder.appendByteList(byte[] value) 将字节追加到 INT8/UINT8 的 LIST
HostColumnVector.ColumnBuilder	HostColumnVector.ColumnBuilder.appendByteList(byte[] value, int srcOffset, int length) 将字节数组追加到 INT8/UINT8 的 LIST
HostColumnVector.ColumnBuilder	HostColumnVector.ColumnBuilder.appendDecimal128(byte[] binary) 接受一个包含未缩放值的二进制补码表示的字节数组，该表示采用大端字节序。
HostColumnVector.ColumnBuilder	HostColumnVector.ColumnBuilder.appendLists(List... inputLists)

HostColumnVector.ColumnBuilder	HostColumnVector.ColumnBuilder.endList() 如果您想构建一个列表列，您可以获取 `builder.getChild(0)` 并向其追加数据，然后完成追加后调用 `endList`，此时追加到该 builder 的所有内容都将成为下一个列表中的数据。
HostColumnVector.ColumnBuilder	HostColumnVector.ColumnBuilder.endStruct() 如果您想构建一个结构体列，您可以获取每个子 builder `builder.getChild(N)` 并向所有子 builder 追加数据，然后完成追加后调用 `endStruct` 以更新此 builder。
HostColumnVector.ColumnBuilder	HostColumnVector.ColumnBuilder.getChild(int index)
