improve performance of related entities retrieval #62
Description
Hi,
we encounter performance issues with related entities.
Given we make this API call:
GET https://api/articles/12345678-4792-11e7-88db-f23c9124c2b0
Which returns :
{
"@context": "\/contexts\/Article",
"@id": "\/articles\/12345678-4792-11e7-88db-f23c9124c2b0",
"@type": "Article",
"id": "12345678-4792-11e7-88db-f23c9124c2b0",
"title": "foo bar",
"tags": [
"\/tags\/331a2c47-164a-11e7-8a8a-f23c9124c2b0",
"\/tags\/331a658c-164a-11e7-8a8a-f23c9124c2b0",
"\/tags\/331a71cc-164a-11e7-8a8a-f23c9124c2b0",
"\/tags\/9c828580-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9c82e2b1-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9c834c02-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9c850c8b-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9c86ca17-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9cc9f244-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9cd4d60e-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9d186137-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9d194643-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9d1f1245-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9d1fe224-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9d33f4f4-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9d37d44d-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9d4353fe-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9d5d71fd-75f3-11e7-8820-f23c9124c2b0",
"\/tags\/9da0e8d6-75f3-11e7-8820-f23c9124c2b0"
]
}
When we iterate over the entity tags collection ($article->getTags()), each iteration makes an API call to retrieve the tag entity:
GET https://api/tags/331a2c47-164a-11e7-8a8a-f23c9124c2b0
GET https://api/tags/331a658c-164a-11e7-8a8a-f23c9124c2b0
GET https://api/tags/331a71cc-164a-11e7-8a8a-f23c9124c2b0
GET https://api/tags/9c828580-164a-11e7-8a8a-f23c9124c2b0
...
Which kills the performances of our application.
Embedding the tags in the article API response is not an option in our case (for a lot of reasons).
So my question is: is there a way to tell the API client to retrieve all the tags at once instead of retrieving them one by one ?
