Details of Mongodb chunk Migration?

  mongodb, question

Have a look at MongoDB’s documentation aboutChunk migration description, I still have a few questions:

  1. Does destination chunk start synchronizing update to source chunk during migration after replication is completed?

  2. How does destination chunk confirm that it is Fully Synchronized? What if there are new write requests when destination chunk updates config server’s metadata? After the global route is changed to the new chunk, will some of the updates be missed?
