HttpClient httpClient = new StdHttpClient.Builder(). url("http://yourcouchdbhost:5984"). username("admin"). password("password"). build(); CouchDbInstance dbInstance = new StdCouchDbInstance(httpClient);

Given you have a valid CouchDbInstance instance, you connect to a database within CouchDB in the following manner CouchDbConnector connector = dbInstance.createConnector("databaseName", true);

If you want to detect missings with df=pd.DataFrame({'col':[1,np.nan]}) df==np.nan you will get the following result: col 0 False 1 False This is because comparing missing value to anything results in a False - instead of this you should use df=pd.DataFrame({'col':[1,np.nan]}) ...
