As observed in SERVER-73106, the meaning of the default-constructed WriteConcernOptions() is dependent on the presence of getLastErrorDefaults in the replica set config. It may be worthwhile to audit the usages of the default-constructed WriteConcernOptions() in other areas of the sharding codebase:
- https://github.com/mongodb/mongo/blob/r4.4.18/src/mongo/db/s/config/sharding_catalog_manager_chunk_operations.cpp
- https://github.com/mongodb/mongo/blob/r4.4.18/src/mongo/db/s/sharding_state_recovery.cpp
Explicitly specifying a {w: 1} write concern for internal operations will prevent getLastErrorDefaults in the replica set config from an effect.
const WriteConcernOptions kNoWaitWriteConcern{1, WriteConcernOptions::SyncMode::UNSET, Seconds(0)};
