| Description |
|
As part of the resharding effort we need to run a pipeline with the collection's default collation, but then use the simple collation for a specific comparison concerning the chunk boundaries. This ticket tracks the work to add that ability. Note this is different and narrower than SERVER-25954, since we need this relatively soon and it is believed that SERVER-25954 is a pretty substantial engineering effort. |
