I am facing the same problem. I set up facerecognize on existing dataset with 92918 images. The background_job finished successfully. In the settings > Facerecognize, when I click "Review people found", the API call to clusters endpoint fails with Gateway timeout error. There are 73109 faces with 33746 clusters.

For another user with 15253 images, 13354 faces and 5911 clusters, the API is able to respond in time.

I am using dockerize nextcloud. I have manually set up PDLIB. Here's the reference to docker image: https://github.com/mrishab/anton-apps/blob/master/nextcloud/Dockerfile.

I was actually able to resolve by increasing the timeout setting on my reverse proxy. The request does take about a minute to respond but it's still workable.

Hi, The code for this function is somewhat archaic. Since I hope to recommend Memories, I haven't spent enough time on it yet.
I still ask you, did you try memories? It is important because if it is more responsive it should do a similar implementation

[axeljerabek]

Well, "responsive" is maybe something else. But it is way faster at least. The problem is not to show the persons, but the button itself takes ages to show the clusters. And the "review people found" button does not exist in memories. The problem also did not occur in the older versions with about the same amount of persons/clusters. It exists mostly since the introduction of those two buttons on top, with the ignored persons.

[matiasdelellis]

Just leave it here for reference..

SELECT person, COUNT(*) AS FacesCount
FROM `oc_facerecog_faces` AS Faces
INNER JOIN `oc_facerecog_images` AS Images ON Images.id = Faces.image AND  person IS NOT NULL
INNER JOIN `oc_facerecog_persons` AS Persons ON Persons.id = Faces.person AND  name IS NULL
WHERE Persons.user = 'test'
GROUP BY person
HAVING FacesCount > 3
ORDER BY FacesCount DESC
LIMIT 50

I would have to implement a similar sentence, but for me it is still slow. 😞

Now, it does not react anymore if the "review people found" button is clicked.
