Chapter 06, page 157 should read:

Adding load_eq_data()

The only significant differences in our file load subroutine, called load_eq_data() is the encoding of the data to accommodate Unicode (UTF-8) characters:

    data = input_file.read().encode('utf-8')

and the specification of time precision in milliseconds (ms):

response = requests.post(url, params=dict(db=db_name, precision="ms"),
data=data)

Chapter 08, page 204 should include additional lines:

To load the data into ElasticSearch, run the following command:

% docker-compose run logstash logstash < data/Current_FY_Cases.csv

For Windows PowerShell, the command is:

Get-Content .\data\Current_FY_Cases.csv | docker-compose run logstash logstash
