  • Restrictions and Limitations

Capped Collections are fixed-sized collections that support high-throughput operations that insert and retrieve documents based on insertion order.

Steps

1

Click the Create Collection button

From the Collections screen, click the Create Collection button.

2

Enter the collection name

3

Click the Additional preferences dropdown

Check the Capped Collection option.

4

Enter the size of the capped collection

Enter the maximum number of bytes that the collection can hold.

5

Click Create Collection to create the collection

Restrictions and Limitations

The following restrictions and limitations apply when creating a capped collection:

  • Custom collation is the only Advanced Collection Option that can be used alongside your capped collection.

  • If you import a data set larger than the maximum size of the capped collection, Compass only loads the last documents of the data set and drops the oldest documents.

  • Once the collection is created, you cannot adjust the maximum number of bytes.
