I need to bulk update a datastore with a CSV file (250,000 rows) using Python. From researching this area, I can see that MapReduce would suit this problem.
I have found some examples showing similar actions but can’t seem to find an example of how to do a simple Bulk Update of a datastore using this library.
Do you know of any examples in this area or would you be able to point me in the right direction please?
Thanks

You can also use the bulk uploader to upload data from csv to the datastore.
