I get an odd error while batching data to Azure table storage.

I have an array with +350.000 strings. I save each string in a row. It Works fine until the firste +50.000 records then the Azure table storage starts to throw an exception with “invalid inputtype” and a “statuscode 400”.

When I batch, I batch 10 items at a time, with a simple retrypolicy.

_TableContext.RetryPolicy = RetryPolicies.Retry(4, new TimeSpan(0, 0, 30));
_TableContext.SaveChanges(System.Data.Services.Client.SaveChangesOptions.Batch);

No async, no parallism. It Works fine on Dev environment.

Grrr…

    There is a physical limit in the Azure Table Storage of 1MB per row, and a limit of 64 Kb (Kilobytes) per string field.

    Also, if you are storing the strings as partitionkeys or rowkeys then some characters are not allowed.
