I'm closing out the master ticket, SERVER-49664. Here's the remaining documentation work I've thought of and presume this ticket will cover – or it can be split off from here to additional tickets.

  • ViewCatalog is copy on write now
  • Decorables are copyable now
  • The oplog collection is special and not copy-on-write
