Creating a custom python data pipeline

Having pushed the data in MySQL using a Google App script I wanted to see whether I could then push the data to Snowflake without using one of the automated tools. I decided, initially at least, to use python. Python is a very easy language to use and to achieve the basics, for this sort of project at least, you can plug and play with packages that you need. This is not going to be the most performant and probably won't fly in a proper Enterprise environment though I have previously used complex scripts to generate BI reports for the majority of a companies (start up) reporting. 

Below is my script minus the creation of the connection engines, because for the purposes of this I did not want to go to the trouble of masking them and it is very well documented how to create them. Currently I am running this manually but for £5 a month I can get this scheduled on pythoanywhere but hoping I will pluck up the courage to run this on free tier Azure. 

from snowflake.connector.pandas_tools import pd_writer
import pandas as pd
from sqlalchemy import create_engine
import pandasql as ps
#Create MySQL Connection
mySQL_conn = create_engine("");
#Create SnowFlake Connection
Snowengine = create_engine("")
#Fetech Data from MySQL Weather table into dataframe
df = pd.read_sql_query('select * from weather where locationName is not null and LocationRegion is not null',mySQL_conn);
#Transform the data using pandas SQL, because SQL is simple and easy to follow
get_cols = ps.sqldf("select LocationName , LocationRegion , LocationCountry , LocationLat , LocationLon , CurrentLastUpdated , CurrentTempC , CurrentConditionText, CurrentWindMph, CurrentPrecipMm , CurrentHumidity , CurrentCloud, CurrentFeelslikeC FROM df")
#Load the processed dataframe into Snowflake
get_cols.to_sql('stg_weather', con=Snowengine, if_exists='replace',index=False, method=pd_writer);

AWS training cloud academy free course

One of the things I like about this course are the instructors are really clear but also that it provides free labs that allow you to actually sign into AWS and perform some actions to actually create and do things without worrying that you are going to incur a cost.  Today I complete one of the hands on labs.  This was to create a lambda function, in this case it was a very basic python script that was searching a website for a keyword. I then placed this into a schedule and used cloudwatch to create a dashboard that monitored the running of this function. Overall it was a very simple use case but it was also a very simple process to setup.  I don't have much to add to this other than it is well worth signing up to cloud academy for the free training if nothing else, I am tempted, once i have done some more training, to give the paid for option a go to get the full sandboxes.

Data Cleansing View in Snowflake

For part of one of my free ETLs I am using Zapps to transfer e-mails from Google Sheets and then Keboola to transfer the sheets into my Snowflake database. I am familiar with string searches and cleansing in Oracle and using python but have not had the chance to do this in Snowflake. I wanted to give it a go as a proof of concept if nothing else. There were some difference in functions between Oracle and Snowflake, no INSTR and using POSITION instead and some difference in working with dates / timestamps but overall it was very similar.  The code below is what I ended up using:  I think want to use this to create some overview graphics to allow me to track the success or failure of my ETLs. Assuming the aspects of Retool remain free you can see how much ETL is going on this link .  In case things aren't working, here is a table of the output I am producing.
