This example shows how a different file system service can be injected
|
|
into a transformation (as compressing pickled objects often makes sense
|
|
anyways). The pickle itself contains a list of lists as follows:
|
|
|
|
```
|
|
[
|
|
['category', 'sms'],
|
|
['ham', 'Go until jurong point, crazy..'],
|
|
['ham', 'Ok lar... Joking wif u oni...'],
|
|
['spam', 'Free entry in 2 a wkly comp to win...'],
|
|
['ham', 'U dun say so early hor... U c already then say...'],
|
|
['ham', 'Nah I don't think he goes to usf, he lives around here though'],
|
|
['spam', 'FreeMsg Hey there darling it's been 3 week's now...'],
|
|
...
|
|
]
|
|
```
|
|
|
|
where the first column categorizes and sms as "ham" or "spam". The second
|
|
column contains the sms itself.
|
|
|
|
Data set taken from:
|
|
https://www.kaggle.com/uciml/sms-spam-collection-dataset/downloads/sms-spam-collection-dataset.zip
|
|
|
|
The transformation (1) reads the pickled data, (2) marks and shortens
|
|
messages categorized as spam, and (3) prints the output.
