I'm trying to use InsertBatch to process a ~300MB file. I use File.Readlines to enumerate the lines in the file and turn them into BsonDocuments. I pass the LINQ enumerator to InsertBatch - it just hangs. It works fine with a small file.

It does the same thing if I manually batch by using Skip & Take on my LINQ query which is pulling lines out of the file. If I take the first 5000 lines and pass them to InsertBatch the first call works and the second 5000 batch just hangs.

I thought it might be something to do with one of these
https://jira.mongodb.org/browse/CSHARP-717
https://jira.mongodb.org/browse/CSHARP-715

but am pretty stuck to be honest. Help!

code snippet:

var postcodesToInsert = File
.ReadLines(csvFile)
.Select(
postcode =>
new BsonDocument
{

{ "Postcode", postcode.Split(',')[0].Replace(" ", string.Empty) .Replace("\"", string.Empty) }

});

postcodesCollection.InsertBatch(postcodesToInsert);

thanks
Nic
