How to retry bulk import if it fails or not imported all document in one batch/call.

[AjitBhosale]

executing bulk import with following configurations -

1. MaxRetryWaitTimeInSeconds and MaxRetryAttemptsOnThrottledRequests set to 0.
2. Importing document without id, enableUpsert is flase and disableAutomaticIdGeneration is false.

3. code -

   do { try { bulkImportResponse = await bulkExecutor.BulkImportAsync(bulkDocument, false, false); } catch (Exception e) { // log exception } } while (bulkImportResponse.NumberOfDocumentsImported < bulkDocument.Count());

So if it throw any exception during documents insertion(line 5) than it will rollback inserted document internally or not? if not than i require to remove NumberOfDocumentsImported from bulkDocument before retry with do-while loop?

If the batch fails, you can simply re-run the BulkImportAsync method with the same batch of documents, but this time, with enableUpsert set to true.

As a pre-processing step for a scenario such as this, we would also recommend assigning Guids as ids for the documents to avoid duplicates when retrying the batch.
