How can I save a table in C# Apache Arrow to a file on disk?

edit

To save a table in C# Apache Arrow to a file on disk, you can use the ArrowStreamWriter class. Here's an example code snippet:

using(var stream = new FileStream("data.arrow", FileMode.Create))
using(var writer = new ArrowStreamWriter(stream, table.Schema))
{
    writer.WriteTable(table);
}

In this code, table refers to the Table object that you want to save, and data.arrow is the file name of the output file.

First, a FileStream object is created to specify the output file and the FileMode as Create to create a new file.

Next, an ArrowStreamWriter object is created by passing in the FileStream object and the schema of the Table.

Then, the WriteTable method of the ArrowStreamWriter object is called to write the Table to the output file.

Once the write operation is completed, the file is saved on disk.
