Can you explain more information about the word "database"? It will be understandable if we are talking about deleted data such as the deleted message in the Instagram application, but how will you get private account pictures from an application banned from the Google Play Store?

The key to expanding Instagram data centers is to distinguish between global data and local data. Instagram uses the PostgreSQL and Cassandra background databases, in other words, not all data is stored in a single server (Database).

Just as such things violate privacy, I do not think Instagram will be vulnerable in such settings, all of its subscribers will be lost.
