Redis Cache: change keys and values

[diesalbla]

The purpose of this ticket is to define the datatypes for the new format of keys and values that are to be stored in the Redis Cache.

Each key will be a record that will contain the following fields:

• Package name of the app
• The type, or status, of the entry. This one could be pending, permanent, resolved, or error.
• Optional: the dateTime (let us use UTC time zone) in which the error was caused.

The types of the values stored will depend upon the type of the key.

For resolved or permanent entries, the value will be a FullCard.

For other responses, the value would have no information.

The instructions for the QA are as follows.

1) In a terminal session open the Redis Client redis-cli, and clear the cache executing the command flushAll. 2) In another terminal, run the google-play backend application, using the application.conf configuration file.

sbt -Dconfig.file="src/main/resources/application.conf" run

3) With a valid androidId and token, execute the following command (a call to the endpoint to get many cards):

curl -X POST \ 
  -H "X-Google-Play-Token: <TOKEN>"\
  -H "X-Android-ID: <ANDROIDID>"\
  -H "Content-Type: application/json"\
  --data @body.txt \
  "http://localhost:8081/googleplay/cards"

where body.txt is the file attached to this message.

4) In the terminal with the redis-client, look up the contents of the cache.

• Execute the command keys "*" to see all the keys. You should see the new format, with either the words Pending or Resolved in them. There should be one key for each package in body.txt.
• If you execute keys "*Resolved*", you should be able to see those resolved packages. These should correspond with those for which a card was returned by the endpoint.
• If you execute keys "*Pending*", you should see the packages for which no card was found.
• If you copy one of the resolved keys, you should get the Json format of a full card. To see this in a more convenient manner, you can exit the redis-client and execute the following command:

echo 'keys "*Resolved*" '  | redis-cli | sed 's:\":\\\":g;s:\(.*\):get "\1":' | redis-cli  | jq .

• If you do the same with a pending keys, the result should just be all null.

echo 'keys "*Pending*" '  | redis-cli   | sed 's:\":\\\":g;s:\(.*\):get "\1":' | redis-cli  | jq .

Note: the androidId and token do not need to be authenticated, since the operations on the cache are also done with the results from the Web Scrapper.
