I am trying to read the content of an arrow file but I was not able to find
the functions to get the actual data from it. I am not able to find any useful
example to read the data too. For example here.
The code example for writing and reading in C#:
`
// Write
var recordBatch = new Apache.Arrow.RecordBatch.Builder(memoryAllocator)
.Append("Column A", false, col => col.Int32(array =>
array.AppendRange(Enumerable.Range(5, 15))))
.Build();
using (var stream = File.OpenWrite(filePath))
using (var writer = new Apache.Arrow.Ipc.ArrowFileWriter(stream,
recordBatch.Schema, true))
{
await writer.WriteRecordBatchAsync(recordBatch);
await writer.WriteEndAsync();
}
// Read
var reader = Apache.Arrow.Ipc.ArrowFileReader.FromFile(filePath);
var readBatch = await reader.ReadNextRecordBatchAsync();
var col = readBatch.Column(0);
`
By debugging the code, I can see the values in the col Values property but I
have no way of accessing this information in the code.
Am I missing anything or is there a different approach to read the data?
