I'm getting several exceptions like the one below in bulk indexing.

```auto
u'error': {u'caused_by': {u'reason': u'Java heap space', u'type': u'out_of_memory_error'}, u'reason': u'failed to parse', u'type': u'mapper_parsing_exception'}

```

I'm indexing documents with an array field with a big number of elements (may be 1000 - 10000 order of magnitude). Each element is a small json object. These documents have a big size: some of them are about 3MB.  
I take care of not exceeding the payload limit of the bulk indexing, so I suspect the typology and size of the documents I'm indexing can be the root cause of the exceptions.  
Is there any limit on the size of a single document that can be ingested? If not, is there any configuration parameter that I can tune to fix the problem?  
I'm running a single node elasticsearch, with default configuration.  
Thanks in advance.
