Downside to using Bulk API for small/single-doc sets?

Hi,

I am using ES Java API to talk to an ES server. Sometimes I need to index a
single doc, sometimes dozens or hundreds at a time. I'd prefer to keep my
code simple (am a contrarian thinker) and wonder if I can get away with
always using bulk API (ie BulkRequestBuilder). so that my interface to ES
would look like so:

void indexDoc(Doc doc);
void indexDocs(Collection docs);

...but impl would always delegate to BulkRequestBuilder - with number of
actions sometimes being ~ 1.

Is there a performance (or other) downside to this approach. Specifically,
would bulk index updates (with set of size == 1) take significantly longer
than non-bulk updates?

thanks,
-nikita

A question back: do you observe a significant difference?

I do not. But I also do not if my tests recreate conditions where
differences may surface.

Yes, the difference is not noticeable. Bulk requests have an extra logic
for shard splitting, with a single index request, there is no overhead at
all.
