Replica Node of SequoiaDB
All operation need deal with the error code returned first, if it has.
Every error code is not SDB_OK(or 0), it means something error has appeared,
and user should deal with it according the meaning of error code printed.
@version: execute to get version
>>> import pysequoiadb
>>> print pysequoiadb.get_version()
@notice : The dict of built-in Python is hashed and non-ordered. so the
element in dict may not the order we make it. we make a dict and
print it like this:
...
>>> a = {"avg_age":24, "major":"computer science"}
>>> a
>>> {'major': 'computer science', 'avg_age': 24}
...
the elements order it is not we make it!!
therefore, we use bson.SON to make the order-sensitive dict if the
order is important such as operations in "$sort", "$group",
"split_by_condition", "aggregate","create_collection"...
In every scene which the order is important, please make it using
bson.SON and list. It is a subclass of built-in dict
and order-sensitive
