Overhead in put() due to debugging info #1034
Description
While profiling our NDB app, I noticed protobuf __repr__ calls appearing higher than expected in our total profile. According to the profile, These are called from within put() in _datastore_api.py.
As far as I can tell, the culprit seems to be this line, which serializes a text representation of the entire RPC put command into the info field. Could it be that this creates unnecessary overhead for large entities?
