Testing Multiple Versions

In this section we'll update data created with version 1.0.0 of country to add a value for continentName value and show how clients that continue to use the older 1.0.0 version are not impacted.

Set continentName

Since we only have two contries, US and CA, we'll issue an update to set all the documents.

curl -H Content-Type:application/json -X POST  -d '{
  "projection": { "field":"*","recursive":1},
  "query": { "field": "objectType", "op": "=", "rvalue": "country" },
  "update": [ { "$set": {"continentName": "North America"} } ]
}' ${BASE_URL}/rest/data/update/country/1.1.0

Verify version 1.0.0

We'll use a simple query and project fields iso2Code and continentName.

  • version 1.0.0 still works
  • client asking for a field it cannot access doesn't break
  • version 1.0.0 does not see the new continentName field
curl ${BASE_URL}/rest/data/find/country/1.0.0?Q=iso2Code:US\&P=_id:1,continentName:1

Verify version 1.1.0

The same query is used to verify version 1.1.0 by simply changing the version in the URL.

  • version 1.1.0 works
  • client sees field continentName
curl ${BASE_URL}/rest/data/find/country/1.1.0?Q=iso2Code:US\&P=_id:1,continentName:1
