BulkInsertBuilder class

Builder for creating bulk insert data buffers.

Provides a fluent API to define table structure, columns, and rows for efficient bulk insert operations.

Rows passed to addRow are stored by reference; do not mutate a row list after it is added (wrap with List.unmodifiable when the same list instance might be reused elsewhere).

Example:

final builder = BulkInsertBuilder()
  ..table('users')
  ..addColumn('id', BulkColumnType.i32)
  ..addColumn('name', BulkColumnType.text, maxLen: 100)
  ..addRow([1, 'Alice'])
  ..addRow([2, 'Bob']);
final buffer = builder.build();
