      Hello,

      I am trying to upgrade our MongoDB 4.2.1 replica set to 4.4.2. Our Spring Boot 2.4 application with Java driver 4.1.1 uses multi-documents transactions and manipulates lots of documents in the same transaction (batch writting).

      We do not have any issue on MongoDB 4.2 but theses transactions fails on WriteConflict on 4.4.

       

      I add here a Java/Spring simple unit test case which pass on mongo 4.2 but not on mongo 4.4 which do the following :
       

      • init the collection outside the transaction with 20 000 docs (with 2 properties, id and string with 1000 chars)
      • in a transaction, removes all the 20 000 docs and re-insert 20 000 similar docs

      Step to reproduce : 

      • Run the following test on mongo 4.2.1 : it passes 
      @RunWith(SpringRunner.class)
@ActiveProfiles(value = "test-mongo44")
@Import(
        {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class}
)
@SpringBootTest()
public class Mongo44Test {
    @Autowired
    private MongoTemplate mongoTemplate;    
    @Autowired
    private MongoTransactionManager mongoTransactionManager;    

    @Test
    public void test1() {        
       // init the collection with 20 000 docs with a 1000 chars length string
        Collection<Document> elements = new ArrayList<Document>();
        IntStream.range(0,20000).forEach(i -> {
            Document doc = new Document();
            doc.put("id", "site");
            doc.put("string", RandomStringUtils.random(1000, true, true));
            elements.add(doc);
        });
        mongoTemplate.insert(elements, "mongo44");        
         TransactionTemplate transactionTemplate = new TransactionTemplate(mongoTransactionManager);
        transactionTemplate.execute(new TransactionCallbackWithoutResult() {           
           @Override
            protected void doInTransactionWithoutResult(TransactionStatus status) {
                // remove all docs in transaction
                mongoTemplate.remove(Query.query(Criteria.where("id").is("site")), "mongo44");
                elements.clear();
                // and re-insert 20 000 docs with a 1000 chars length string in the transaction
                IntStream.range(0,20000).forEach(i -> {
                    Document doc = new Document();
                    doc.put("id", "site");
                    doc.put("string", RandomStringUtils.random(1000, true, true));
                    elements.add(doc);
                });
                mongoTemplate.insert(elements, "mongo44");
            };
        });    }
}
      • Run the same test on mongo 4.4.2 : it fails on following error
