python 2.7 - Elastic search memoryerror on bulk insert -


im inserting 5000 records @ once elastic search total size of these records is: 33936 (i got using sys.getsizeof())

elastic search version: 1.5.0 python 2.7 ubuntu

here following error 

traceback (most recent call last):   file "run_indexing.py", line 67, in <module>     index_policy_content(datatable, source, policyids)   file "run_indexing.py", line 60, in index_policy_content     bulk(elasticsearch_instance, actions)   file "/usr/local/lib/python2.7/dist-packages/elasticsearch/helpers.py", line 148, in bulk     ok, item in streaming_bulk(client, actions, **kwargs):   file "/usr/local/lib/python2.7/dist-packages/elasticsearch/helpers.py", line 107, in streaming_bulk     resp = client.bulk(bulk_actions, **kwargs)   file "/usr/local/lib/python2.7/dist-packages/elasticsearch/client/utils.py", line 70, in _wrapped     return func(*args, params=params, **kwargs)   file "/usr/local/lib/python2.7/dist-packages/elasticsearch/client/__init__.py", line 568, in bulk     params=params, body=self._bulk_body(body))   file "/usr/local/lib/python2.7/dist-packages/elasticsearch/transport.py", line 259, in perform_request     body = body.encode('utf-8') memoryerror

please me resolve issue.

thanks & regards, afroze

if had guess, i'd memory error happening within python loads , serializes data. try cutting way on batch sizes until works, , binary search upward until fails again. should figure out safe batch size use.

(other useful information might want include: amount of memory in server you're running python process on, amount of memory elasticsearch server node(s), amount of heap allocated java.)

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
