sync program between Atlas clusters (mongosync / mongomirror)
Here’s my question – about mongosync (mongomirror). It’s more likely feature request.
So the new sync program can utilize “filter” to select what document or collection to sync. It will be awesome if we can utilize mongo atlas change stream in source.
Source: SL1 Database: SDB1
Target: TL2 Database TDB1
SL1 SDB1, capture “remove document” event for collection A -> Send to target TS2, TDBA, Collection A as “insert” via sync program
By doing this, we can roll ower own “archive” cluster, TL2. Federate SL1 and TL2 collection A to query current and old document.
