Add support for composite types to Appender #191

Open Giorgi opened 5 months ago

Add support for writing composite types (List, Array, Struct, etc) with Appender.

Giorgi commented 5 months ago

Lists and Arrays are now implemented.

I'm using using a RowAppender to bulk insert a 1.5M rows with 2 fields, and Integer and List<double?>.

I get an exception:

An unhandled exception of type 'System.AccessViolationException' occurred in Unknown Module.
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

It seems to work fine when I reduce the number of rows to 5000.
