      Inefficient vector resizing with reserve.

      This operation, if performed to grow large vectors, may take a very long time to complete. A vector's capacity is increased with reserve in a manner that causes many unnecessary copies.
      /src/mongo/db/modules/enterprise/src/streams/management/stream_manager.cpp:1270: INEFFICIENT_RESERVE 155468 A "std::vector" has its capacity adjusted with "reserve()" in a manner that is likely to have severe performance penalties.
