I have found a lot of 'limits' from MongoDB.



if your configurate a limit on Items in a Collection the limit is less than 2^32. The default Value for the number of Collections is 24000. But what is the max amount of databases?

  • The limits you are describing are for the older (and now deprecated) MMAP storage engine. See MongoDB Limits & Thresholds in the manual for your version of MongoDB server. Many limits no longer apply in modern versions of MongoDB using the WiredTiger storage engine.
