    Description

      Issue,
      Chained Replication is enabled by default in all supported MongoDB Server releases, and this means that a SECONDARY might select another SECONDARY as a sync target with large replication lag but very low ping time.

      Metadata,

      • MongoDB Server version: v. 4.0.X, v. 4.2.X, v. 4.4.X, v. 5.0.X

      What we need from this SERVER ticket,

      • Can we consider enhancing Chained Replication feature by adding ability to configure sync target based on staleness time?
        • Here is the diagram to describe the proposal,

      Thanks in advance,
      Alexey
