Review Comment:
I understand UTF-16 -> UTF-8 does not necessarily imply 50% reduction.
We decided to show the error message.
Let's say, I change it to
```
catch (BsonMaximumSizeExceededException e) {
LOG.error("Failed to create one of the documents from the
below list " +
" with BsonMaximumSizeExceededException message =
'{}'.", e.getMessage());
for (T doc : docs) {
LOG.error("Document ID {} and Size {} ",doc.getId(),
doc.getMemory());
}
return false;
}
```
```
13:01:03.511 ERROR [main] MongoDocumentStore.java:1494 Failed to create
one of the documents from the below list with BsonMaximumSizeExceededException
message = 'Payload document size is larger than maximum of 16777216.'.
13:01:03.511 ERROR [main] MongoDocumentStore.java:1494 Document ID
/test and Size 2097764
13:01:03.511 ERROR [main] MongoDocumentStore.java:1494 Document ID /foo
and Size 33557724
```
The exception message from Mongo shows the size limit as 16777216 and we are
calculating it with doc.getMemory(). So a document with size 16778862 will show
33557724 with doc.getMemory().
Should I also log that BSON size is calculated in UTF-8 and we are doing it
in UTF-16?
