 Description   

Description

The page https://docs.mongodb.com/manual/tutorial/clear-jumbo-flag/ mentions:

If MongoDB cannot split a chunk that exceeds the specified chunk size or contains a number of documents that exceeds the max, MongoDB labels the chunk as jumbo.

It's not clear what max is. I think this limitation was removed by SERVER-19919, so this is outdated?

Scope of changes

  • Sync with Sharding team to understand what the impact of the linked server ticket is
  • Validate what the behavior was before that ticket
  • Update documentation for 4.2, 4.0, 3.6 (if necessary)

Hi kay.kim, I had a chat with linda.qin about that max, and she didn't think it's referring to the Max number of documents per chunk to migrate. We were thinking that the original intention of the text was referring to the 250,000 max documents per chunk (which the balancer would try to split, failed, and mark the chunk as jumbo), but this was changed in SERVER-19919.

I really don't know if the "max" mention be removed, or should it link to the "max number of documents per chunk to migrate".
